Pick a card. 

Talk for 30 seconds about it without saying um, ahh, like, so. 

No long pauses and no repetition.

Don't know the topic? 
Make it up with the confidence you shouldn't have.

Survive the timer? 
Win the card. 

Player with the most cards wins.

The rest is up to you.
Who starts, how strict, what counts as a long pause and repetition, how many cards until you win. Your group, your call.

Call out someone for making it up with the confidence they shouldn't have.

You can call out a player for bluffing on a fact-based card, either during their turn or before the next player starts theirs. 

Once you call their bluff, the clock stops but you'll need proof (nothing a quick search online can't settle).

Right? Steal their card.
Wrong? They win the card automatically without needing to finish their turn, AND they steal one of yours.
No card to give? Miss a round.

Think 30 seconds is too easy? Extend it.

Think our list of forbidden words is too small? Add more.

Extend it: add extra time.
Add more: add your own forbidden words to the list.

Pick a dealer. Give them 30 seconds to raid the deck and deal everyone a hand-picked card, face down. Themselves included.

Flip and yap: one at a time, survive your card and win it, fall apart and the dealer takes it.
New dealer: at the end of the round, the dealer role passes to the next player.

Pick a card, one topic, passed around. Survive your 30 seconds and the card moves on to the next player.

No repeats: next player can't repeat what's already been said.
No filler: drop a filler word, stall or repeat and the card is yours.
Win it: player with the fewest cards wins.
Burn it: make it all the way around with no casualties? Burn the card, nobody wanted it anyway.
