The "Back and forth" poop sign popularized by the movie "Me, You, and Everyone We Know" the )) and (( are two butts, and the <> is poop going back and forth between the two butts. This was supposedly "invented" by a young boy talking to a 40 year old woman on a chat room and pooping "back and forth, forever" is his idea of romance.
