A trick
A guy who lets ladies take advantage of him. A trick is also a guy who acts like a total idiot for a woman or a woman who acts like a tease to make guys look like total idiots.
My dude got conned by a girl who said she was gonna marry him after one date.
My friend was so dumb he let his ex borrow his car and never got it back.
My cousin said he was gonna marry a girl just because she smiled at him.
