“Twat” Mug

At first glance, this handsome but ordinary-looking mug doesn't exactly stand out from the crowd but as soon as anyone raises it to their lips to take a drink, the cheeky message printed on the base will clearly be revealed. As everyone except the drinker will be able to read the bold message on the base of the mug, consider this the updated, slightly more sophisticated version of sticking a 'kick me.' Sign to your mate's back. Poke fun at a particular colleague or friend, or leave the mug in the cupboard and let fate decide which unsuspecting tea drinker gets an insult with his or her hot beverage.
