Topless Tuesday 

Possibly one of the best creations ever on Tumblr. Arousing boys since early 2011, girls on Tumblr are supposed to post a picture of themselves without a t-shirt (and sometimes a bra) every Tuesday.

Jack: Why's everyone putting naked photos up on Tumblr?
Dave: It's topless Tuesday!
