look up any word, like dirty sanchez:
 
1.
Two or more 'losers' who are in close proximity of eachother and may be related, although not exclusive. Such bangers may be teenagers or older and sharing a room or living with parents. A banger may also still sleep in a bunk bed. Living in a socially frowned upon situation.
Those three banger brothers still share share a bedroom and the youngest is 21.
