Social networking service that allows its users to send and read other users' updates on their bowel movements (called "twats" or "shits").

Poon: Thanks to Twatter, I get to know not only when my friends take a dump, but also how the shit smelt like, its composition and occasionally, how it tasted!

Donna: I'm glad twats can be sent as text, images, video and audio! Personally, I film my whole defecation and post it for my friends. This occurs in excess of 600 times a day.
