look up any word, like dirty sanchez:
 
1.
noun- mapron is the name given to a man's belly when it has grown full of fat, and hangs over his genital areas like an apron usually worn in the kitchen.
the man was so fat when he goes to the bathroom, he must lift his mapron first.

2.
A man's apron, like waiters wear, with no bib; just around the waist. Usually has pockets.
Ask the waiter for a pen. He's got one; I can see it sticking out of his mapron pocket.
