Top Definition
A boyfriend who is astronomically infatuated with his girlfriend. Common symptoms of becoming a bitch-boyfriend include frequent overprotective behavior and constant communication of his affection, as if he's constantly peeing over a bush to mark his territory. Bitch-boyfriends will usually lose all masculinity and become paranoid of the possible loss of the relationship. This paranoia is not completely amiss, however, as the female will eventually drop the bitch-boyfriend as a result of his excessive neediness.

Guy 2: Yea I know. Let's go find some friends with genitalia.
