A really dumb guy with a big dick or a really big dumb guy who still leeches off of his parents or a guy with no ambitions.
Justin is such a meat wad he amazes me how he can just do nothing.
Wow your boyfriend is such a meat wad at least he's good for one thing!
Meat wad: "Hey Dad I need to borrow some money for rent because I spend my pay check on drugs. No I mean beer."
(He never pays his dad back because he doesn't care. Does it when he needs moany)
That fuck face bitch that you know couldn't hold up in a fight but has a bunch of friends(that are girls so you can't hit them) and all his friends think he's great but whenever he's acting like a fuck face to you and you tell him to fight he comes up with an excuse and his friends(that are girls) take his side and are all like "ya we gotta go loser plus he'd kick ur ass any time."
