: The male version of a lady bug (despite the fact that we all know they're not ALL ladies); but more accurately; your boyfriend, your husband, your main squeeze, your beau, that dude you're loosely seeing but are still laying claim to, the guy you're banging on the regular.
Damn, that manbug of hers really gave it to her last night! I couldn't sleep through all that noise.
