A dirty oheeul is a tackle made in American football, where you drop your helmet into your opponent’s (victim‘s) helmet during a tackle thus rendering them unconscious. While they are unconscious your put your hand round your sweaty bollocks and then wipe said ball and gooch residue onto your sparked out opponents face.

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
