moob tube 

An over-tight t-shirt worn by an overweight man.

Jeff had gained several stone since he last wore the t-shirt, and it now clung to his body like a wet sheet draped over mounds of clay.

"Hey man, nice moob tube," commented one of his friends.

Tube Moob 

Droopy man boobs that, when packed into a too-tight shirt, create a uniboob across a guy's chest.

"That dude should NOT wear Under Armour shirts! It's SO tight it makes his moobs look like a Tube Moob!"
"Check out Home Boy's Tubey Moob - it looks like a uniboob sausage across his chest!"
