F&M 

Facebook masochism. Torturing yourself by obsessively monitoring the page of someone you like, but who doesn't like you. This may also include visiting pages of their friends, family and co-wokers. F&M differs from stalking in that any information gained; seeing what they do, where they go, what's new, etc. only makes you more miserable because you aren't a part of it; yet you can't stop looking.

It's his fault I'm into F&M. He shouldn't have told me he liked me, slept with me and then never called me.

F.M.

Aka as a Faith moment. A moment when someone is so full of themselves that they change the convo so it is about them bc their life is so boring they have nothing else to talk about except themselves

Aimee: I wanna go to the beach tonight
Mikayla: I'm a really good swimmer and like I posted a beach photo on insta last night go like it
Demi: Fuck off Mikayla stop having an F.M.

F.M

-Fresher Mistake.
When you realize that you/someone else has done something silly/regrettable/funny that you would normally expect of someone in their first year at University/College (a fresher).

"Oh dear, last night was a complete F.M, I don't remember anything"

"That guy you got with last night was a bit of an F.M"

After falling down some stairs
"First F.M for the day"

f/m?

Female or male. Shortening of the question "are you a male or female?" Commonly used in random chat sites.

You: F/m?

Them: male

F.M.

Fucking Magic:
1) The idea that something resolved itself; the idea that something resolved magically; Used as an answer when the truth may not be present
2) Shortened version of PFM; a miracle; low probability

The problem cleared itself...how? Not sure, I think it was F.M.
It will be PFM if he/she finishes the job.
