Oisin: street gangster. Great solid fighter has lots of fights and dosnt lose unless hes completely off his face. He will never back down. Highly respected by all even those who hav beef with him*. Plays a wide variety of sports and is especially keen on football and boxing, has a quite muscular body. He is clever, though rarely bothers with studies. The kind of guy youd want as a mate, beside you in a fight, as a lover in the bed. Superior to god and even chuck norris. He drinks and does coke, weed and other drugs , internal organs are half destroyed, its a wonder he can get up in the morning. Devious master when it comes to planning mischief, may well be a gang leader one day. Is good looking and can have any girl he wants and can be secretive when it comes to women. Has an extremely large and impressive cock that he uses alot. Lives different lifes and fits in anywhere.

Girl1: so whats your new boyfriend like?
Girl2: ohh hes such an Oisin, its great.
