Oisin 

oisin is a self centered prick, that enjoys to wank once too many every day. Oisin can fool you into thinking he is trust able and nice, but when he wants to get a bit more popular, he wont be afraid to tell everyone (true or not). he is also extremely clingy to a boy/girl that he likes and can often be seen stalking and following them.

Ugh look at her and oisin. she doesnt even like him

oisin 

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 :(
