look up any word, like sex:

1 definition by Naso

 
1.
Someone who attracts attention, but is actually a loser.

It can be physical - like a heatbag who wears cutoff shirts and expects you to look at him. But reallly he looks like a fag.

It can be psychological - Like someone saying, "yo bro, i just dropped 3 g's on my civic" Fact. He did not spend 3 g's but got a deal off one of his bros.

Origin- someone who drives around in the winter with their windows down blasting music - all while pumping heat in the car so they don't get cold - Heatbagging
Hey guys, look at Tony he's busting out his gay dance moves in front of those girls and he thiks hes actually gonna pick up - What a heatbag
