is a lanky midget who enjoys fondling his tiny minuscule willy. He has no friends and cant take a joke. In short Oisin is a Gayboy who no one likes. He also is terrible at sports and if he plays basketball is pretty much a shit version of Joakim Noah.

Oisin: Pass the ball , I'm open!
John: No you penis fondling prick. You shoot like Joakim Noah and you have no friends , you stupid child rapist!
Oisin: OK :(
