Noun. Derived from the words 'man' and 'seats'.
The seating area often found tactically placed outside the women's fitting rooms in clothes stores for the convenience of the poor men who have to sit and wait whilst their partners do whatever they do in those changing rooms - probably activities such as playing chess, solving world hunger or finding the next prime number, given the amount of time they spend in there.
Man: Excuse me, where are the meats?
Assistant: Sorry sir, we don't have those facilities.
