Tip 1: tag every card with its era
Slang ages fast, and using a dated word is the quickest way to get called unc. Add a hint to each card:
- 2010s / millennial: on fleek, lit, basic, extra, throw shade, OK boomer, yeet, savage.
- Gen Z core (2018-2023): rizz (Oxford Word of the Year 2023), no cap, bussin, slay, mid, sus, hits different, situationship.
- Gen Alpha / brain-rot era (2023+): gyatt, fanum tax, glaze, aura, unc, twin, crash out, cooked.
When you review, ask yourself "would a 16-year-old say this today?" as well as "what does it mean?". That second question is what the deck can't teach on its own.
Tip 2: learn the roots and the pairs
Only bussin gets an origin note, yet much of this deck comes from African-American Vernacular English (cap, bet, finna, periodt) and from Black and Latino queer ballroom culture (throw shade, tea, slay, gagged, snatched, ate). Writing the origin in the hint makes the words stick and helps you use them respectfully.
Also study in contrast pairs, since several cards only make sense side by side: cook (do well) vs cooked (in trouble), W vs L, red flag vs green flag, lowkey vs highkey. One small cleanup: cards 4 (cap) and 5 (no cap) say the same thing, so merge them, and fix the broken front of card 19 to read "flex / flexing".
