The I'm a Twat Mug is a coffee mug with the words "I'm a Twat" printed on the bottom of it so that when the victim takes a sip, everyone can see the words in big black bold text, except the stupid idiot taking a drinking from it. The I'm a twat mug is great gift idea for the office douche, your boss, or just the guy in your group of friends that everyone secretly hates, just make sure they don't look at the bottom of it. The twat mug is made of quality ceramic, is dishwasher safe, and is probably a lot cheaper to just make yourself. Not british enough? Try the I'm a Douche mug which is close to the American equivalent.
