Get the humpy dumpy mug.
Someone with a big dump truck asss. Someone who prefers a dirty bulk diet and is therefore on the larger end (almost pregnant looking). It is vital to avoid these people as they track their calories and spend 3 hours daily at the gym, whilst showing no results but keep saying 'the cut will be insane!'
Have you seen Dylan Wood recently, he's got a fat asss from all that bulking. May as well call him humpy dumpy Dylan!
