A dirty shaun is when your walking down the street you then bum rape a fat guy in the middle of the street run away then marry a girl called ailsa then cheat on her with someone with a forehead the size of mega mind then sweet home Alabama your cousin and then have a massive orgi with hippies and then wank of to monke porn

when you've done something so cringe you can't stop replaying it in your head and it stops you from getting on with your every day life
