A primitive or primitives who cannot fight with words, so always resort to physical violence to assert their dominance over other males. They are defined as "oi cunt"s due to their recurrent use of the phrase.
A group of males are walking along a street when another smaller group of males are walking past. One of the members of the larger group shouts "oi cunt!", generally for no reason at all, some such reasons could include phrases such as "you look like a poof/fag/homo", "your hair/tattoos make you look like..." etc. etc. Then a fight begins to ensue, between the "oi cunt" and a second party who was the target of the "oi cunt"s attacks.
