slick yeah, oi

British expression used when one sees a man or woman spank someone's arse, and then proceed to finger themself in the anus, like the fruity, little fuck they are.

After the victim of the spanking has shown their displease with the harassment in any sort of way, the fruity fuck then proceeds to eat the victim's bumhole.

Witness: Slick yeah, oi! Eat that ass, son, innit yea! You little speng boy, get out of my house!
Victim: o shit, son
Fruity fuck: *om nom nom nom nom nom nom*
