A type of dick head but is circumcised like a filthy Jew. A bellend is either a stupid erotic cunt that likes to toy around with his last bit of foreskin while in the shower with his brother or a prick who cant get his hands of his cock because his sex drive is on a different scale of Jimmy Savile. Chavs use this word a lot because their all circumcised little spazstics. You could also refer a bellend to a bald bloke or a leukaemia infested human.
Jimmy: Boys i managed to stretch my foreskin out so wide my bros head could fit in it
Will: *calls child protection services
Luke: Oi Bellend, your scalps got enough sun you orange looking bastard
Bellend: Cries in Leukaemia
