Scrawl

I had never heard of this game, and so it obviously was not originally on the list, but this was super fun. Scrawl is basically what would happen if you combined Pictionary, Telephone, and Cards Against Humanity into one game.

Here's how it works: Everyone has a little dry erase board and marker. Everyone draws a card with a word or phrase on it (many are naughty... very NSFW and not family-friendly). You draw your card's concept on your little dry erase board, which also has a little clip on it. Everyone passes their board to the next person, who clips a little dry erase sheet over your drawing and writes what they think your drawing is trying to say. Then everyone passes again, and draws what the last person wrote. Continue until you get your original board back. Then you take turns laying out all the cards and reading/showing them, and each person chooses their favorite (like how you choose a card in Cards Against Humanity) and the person who drew/wrote it gets a point.

Here are a few samples of how we did:

There was a lot of discussion about what "burger nips" are.

I definitely picked "the fall of the Muslim nation" as my favorite
for this one, where I drew "Burka breakdancing."

Finally, one of my proudest moments:
What started as "Pinocchio porn" was interpreted as "anteater porn,"
which someone else drew, which I then AGREED WAS "ANTEATER PORN"
which was then drawn again. Amazing. I'd like to thank all my
library patrons for asking vague questions and being unable to
satisfactorily describe their information needs, thus giving me
the practice with this sort of thing that I needed to make this happen.
