US slang for B1 — office and everyday
Slang is the secret handshake of any language community. Use it well and you sound like an insider; use it badly and you sound like you’re trying too hard. This lesson gives you the most common US slang in three tiers: everyday casual, office, and internet/Gen-Z.
Important rule before we start: at B1, your slang priority should be recognition over production. Knowing what touch base means when your boss says it = essential. Saying touch base yourself when you actually meant let’s meet = optional.
Big warning — don’t overuse slang
Three rules of slang for non-natives:
- Match the room. Slang in a job interview = bad. Slang at lunch with coworkers = fine.
- Match the relationship. Slang with a stranger = weird. Slang with a friend = expected.
- Match the slang to your level. Trying out very fresh Gen-Z slang as a non-native is high-risk; many natives over 25 don’t use it either.
When in doubt, use neutral language. Slang is decoration, not the structure of your speech.
Tier 1 — Everyday casual slang
These are heard in any casual American conversation — friends, coworkers at lunch, store clerks, baristas. Safe to recognize and (carefully) use.

Common abbreviations
| Abbrev | Meaning |
|---|---|
| EOD | End of day |
| EOW | End of week |
| COB | Close of business (= EOD, more formal) |
| OOO | Out of office |
| PTO | Paid time off (vacation) |
| WFH | Working from home |

| FYI | For your information |
| ASAP | As soon as possible |
| EOM | End of message |
| NRN | No reply needed |

Mini-example — a Slack exchange
A: hey, can you take a look at the deck? eod is fine B: on it. quick q — should i loop in mark? A: yeah good call, let’s give him a heads up B: sounds good, will do. circling back tomorrow morning A: sounds good!
That’s normal US tech-workplace Slack: short, slang-rich, lowercase, emoji acknowledgment.
Tier 3 — Internet / Gen-Z (recognition only)
These appear constantly online and in Gen-Z conversation. As a non-native, recognize but produce sparingly — they age fast and using them wrong sounds awkward.
| Slang | Meaning | Example |
|---|---|---|
| TBH | To be honest | TBH I didn’t like the movie. |
| IMO / IMHO | In my (humble) opinion | IMO this is the best season. |
| FOMO | Fear of missing out | I have major FOMO about that party. |
| FWIW | For what it’s worth | FWIW, I disagreed with the decision. |
| Ghost (verb) | Disappear from communication | He totally ghosted me after one date. |
| Slay | Do something impressively / look amazing | She’s slaying that outfit. |
| Vibe | Mood / energy | I’m getting weird vibes from this place. |
| Touch grass | Go outside / get off the internet (mocking) | Bro, touch grass. |
| Delulu | Delusional (ironic / playful) | I’m delulu about getting that promotion. |
| Mid | Mediocre / unimpressive | Honestly, the new iPhone is just mid. |
| Bet | OK / sure / agreed | Pick you up at 7? Bet. |
| Rizz | Charisma / ability to charm | He’s got serious rizz. |
| No cap | No lie / I’m serious | That movie was amazing, no cap. |
| Sus | Suspicious | That offer sounds sus. |
| Lowkey / highkey | Slightly / very | Lowkey want to leave early. |
| Salty | Bitter / annoyed | He’s salty he didn’t get invited. |
| Snatched | Looking great | Her hair is snatched today. |
| Bussin | Really good (esp. food) | This pizza is bussin. |
| Slaps | Sounds great (esp. music) | This song slaps. |
| Ate | Performed/dressed amazingly | She ate that performance. |
| Iconic | Memorable / great | That meme is iconic. |
Honest assessment: a 35-year-old at a corporate job won’t say bussin or delulu in a meeting — those are teen / 20-something / online speech. But they’ll say lowkey, vibe, mid, ghost, FOMO casually. Calibrate by who you’re with.
What’s already aging by 2026
- Lit (was massive 2015-2020) — still understood, slightly cringe to overuse.
- On fleek — already aged.
- Bae — aged.
- Yeet — kids still use; for adults it’s playful/ironic.
Slang ages fast. By 2027 some of this list will sound dated. Stay current by listening to current podcasts, YouTube, and TikTok (if you’re young/curious) — not textbooks.
Worked example — same conversation, three slang levels
You’re telling a friend about a busy work week.
No slang (textbook)
I had a very busy week at work. I’m extremely tired. I would like to relax this weekend.
Casual slang (safe)
I’m slammed at work. Totally beat. Just gonna chill this weekend.
Heavy slang (closer friend, casual)
Bro, work has been wild. I’m cooked. Gonna lowkey vibe at home this weekend, no plans.
All three say the same thing. The middle one is the safest default for B1 production.
Common Russian-speaker mistakes
- Overusing slang to sound cool. Sprinkle, don’t pour. Even native speakers don’t use slang in every sentence.
- Using office slang in formal writing. Let’s circle back is fine in Slack/email-to-coworker, awful in a board memo.
- Confusing sick and sucks. Sick = great. Sucks = bad. Don’t mix.
- Using outdated slang. Bae, on fleek, lit, fam — already aged. Stick to the still-current list.
- Producing Gen-Z slang as a non-Gen-Z non-native. Bussin, delulu, slay sound awkward from a 35-year-old non-native in a corporate setting. Recognize, don’t produce.
- Translating slang literally to other slang. Drop the ball doesn’t mean physically dropping anything. Boil the ocean doesn’t involve cooking. Learn meanings, not literal translations.
- Apologizing constantly with my bad. Once or twice in a conversation, fine. Ten times = irritating. Diversify with Sorry about that / That’s on me / Apologies.
- Using slang in job interviews / first emails. Stay neutral until you read the relationship.
Summary
- Three tiers: everyday casual (safe), office talk (essential at work), internet/Gen-Z (recognize, produce sparingly).
- Recognition matters more than production at B1. Knowing touch base when your boss says it is essential; saying it yourself is optional.
- Match the room: no slang in formal contexts, casual slang at lunch, heavy slang only with close friends.
- Slang ages fast — lit is already aging, bussin and delulu may not last. Stay current via real audio.
- Don’t overuse — slang is decoration, not structure.
