M.O.S.

Make Out Session. Normally takes place while intoxicated. Not to be confused with F.O.S which is a fire up session, or a F.I.S. (when you fire inside a girls guts, deposit your kids in the women's belly).

We M.O.S.'ed (pronounced mossed) for a long time.

M.O.S.

man of steel (or 'men')

the 'macho man' who has huge pain tolerance, physically OR emotionally!; ESPECIALLY WHEN DRUNK!!

jack was a true M.O.S.!! he took on some killer bikers and got seriously thrashed, but bounced back like a turd that wouldn't flush!

he didn't know what he was in for challenging those M.O.S.

the special op M.O.S. kept on shooting after losing part of a leg, until he keeled over from blood loss!
