Another way of showing you find something humorous. Synonymous with lol, haha, rofl etc. Different variations show how funny it was (msh, mshmshmsh, MSHMSH!)
Person: Last night's episode was so funny!
Other person: msh, I know.
Person: Oh my God, I've locked myself out of the house.
Other person: MSHMSH! You loser.
"Me So Horny." An abbreviation used to refer to one's increased libido during conversations that occur whilst in public, so as not to offend old people or people with little kids.
One who bitches about things he is not always fully informed of. Also, one who bases his (negative) opinion of something on an early example and refuses to change it when it has improved.
The phrase "Msh" was originally founded at Sunnyside High School by the Blue Devil News team like a few years ago. It was first "nomshk", which was "no I'm just kidding" then it turned to be "msh" then "huhhhhf" and now back to "Msh."
