Your sisters husband or husband's brother, usually older.
The
guy at the family gatherings who makes you uncomfortable by getting drunk, staring and then shamelessly hitting on you then calls you a fat bitch to eveyone else.
Monster In-law is oblivious to the disgusting ways of this child.
The
guy with a chip on his shoulder because he can't get it together and hold down a job.
I bumped into my
Brother-in-law at the grocery

came back with grapes, then proceeded to tell her how ugly I am.
