To cheat, or attempt to cheat, on your partner while he/she is on holiday.

The kind of guy who pretends to be cool with you then goes behind your back and tells people you're a drug addict. A pathetic man child who begs for money online while stalking the web for little kids and then goes full retard at the smell of cigarette smoke and starts punching the walls like a Kyle. Also resembles Hitler, but with Downs Syndrome
