A larvin is a guy that likes to prey on innocent flat-chested girls. He is cocky and thinks he has game like the hero in video games when in reality he nothing but a below average guy that does not deliver. He is a mix of a cocky and a fake guy that any girl (especially under age looking girls) should avoid at all cost.
"That guy? Oh he's a larvin. He may say all these things but he just want to get in your pants cause you look 12."
