The ass on a man which is out of proportion to his body, giving him the appearance of some junk in the trunk, but not in a good way.

a man who is a GREAT piece of ass. Also, a man who has a backside that could melt butter from across the room.
"He is a great piece of man ass." or "This place is filled with great specimens of man ass." or "look at his man ass."

Occurs when you sit on a pubic or office toilet that is gender specific for men and the toilet seat is warm, hot or sticky from the man that just left.
Normally an unused office toilet is cold to the touch but a man ass toilet seat is warm, hot, or sticky.
