Plan M 

"Plan M" (where M = "Masturbation").
A backup plan involving frequent doses of self-administered masturbation if one should fail to find a sex partner.

Person 1: So what's plan B if she's not attracted to you?

Person 2: Well if that's the eventuality, then I'm going to resort to "plan M". Long nights on the couch with my #1 handy man.

Plan F 

this is the girl/guy that you call when you are drunk and horny. You wouldn't have sex with Plan F when you are sober, but you didnt pick up anyone at the bar and cant get ahold of anyone else. Plan F is the person that no matter what time it is, he/she will always let you come over and have your way with them.

GUY1: "Ahh man, I was so wasted last night."
GUY2: "Did you meet up with Kim?"
GUY1: "No, she fell asleep and I couldn't get ahold of any of my other booty calls, so I went to Plan F's house and woke her ass up."
GUY2: "Eww, damn you must have been desparate."

plan laugh 

Referred to in popular American sitcom Friends, in which in one episode Phoebe and Joey concoct an 'evil' plan to get Rachel and Ross back together by setting them both up on terrible dates in the hope that they realise how right they are for one another or something.

But anyway, once they have formed the plan Phoebe points out that this means they can do the plan laugh, which is basically an evil laugh which follows the creation of a good ol' fashioned evil plan. Usually used by villains such as Bond villains etc.

It goes a bit like this, "Muahahahahahahahahahaaaaaaa"

Phoebe: Ooooooh, now we get to do the plan laugh!
Joey: How does that go?
Phoebe: Muahahahahahaaaa
Joey: Oh I get it, wohohohohohooooo...
Phoebe: It's not Santa's plan.
