M.S.S. 

Miss. Squish. Squirt. When doing a classy lady from behind, near ejaculation, one goes in for one last thurst and MISSES, squishing the phallus against her bum cheeks, causing the male to ejaculate into his own ocular region.

Jeremy suffered from M.S.S. and was so embarrassed that he never told his friends.

M.S.S.F.H. 

Mobile Safe Space Field Hospital. (you heard it here 1st cause I coined it) it's like a M.A.S.H. unit that leftards / SJW can seek out when they find themselves in emotional distress after having rallied together to protest Freedom Of Speech in an attempt to protect their hurt feelings. These have been seen erected on public lawns, colleges and university campuses around the country in the US.

S.S.M. 

acronym for Same-Sex Marriage.

I support S.S.M., but I am also straight. I believe that anyone should be married legally to anyone with no problems.
