2) To say something or act in a manner that ultimately blows your chances in a situation with potential.
George Muresan is a gaw.
"I hooked up with that model last night"
"He gets every girl he wants! The man has too much reggaws."
To admire and adore someone silently, fantasizing about them while they sit next to you, completely unaware. Then absolutely gush about him/her to your nearest and dearest friends.
Person B: "So you were totally gawing over him?"
