Quote: ECT "A variation on the peg thing we did in NZ was that everyone had a peg but you could clip yours on to someone else. If done without them knowing they cop the forfeit. But if they catch you it's you who does the forfeit. So it's more risky. Other ones were just saying certain banned words or even using any words that start with a certain letter. Of course most forfeits were just drink related, pushups or at worst some kind of nude activity. None of which appeal to me.'"
That's more for beer circles I've found, otherwise it becomes too difficult to enforce.
In the past, we've found the hardest words to ban were swear words and the word "drink". You can't "drink your drink". You've got to "consume your beverage". Pretty hard to not say the D-word when that's all you're doing!
