An abbreviation for "Man Of a Certain Age".

The phrase originated as the title of a TNT comedy-drama "Men of a Certain Age" from 2010 about three middle-aged men in their late 40's who are about to turn 50.

The abbreviation is mostly used by young gay men to describe an "older" gay man.
His boyfriend is a M.O.C.A.

This bar is good only after 10PM, when the MOCA's leave.
