Plan N 

Method of oral contraception, where the man pulls out and shoves it down the girls neck during ejaculation. 100% effective at preventing pregnancy.

I don't have any condoms but I practice Plan N, were safe.

Plan N 

All the other plans failed, and you have to resort to any way possible to eliminate remaining Africans.

"Boys look, Plan M failed, we have to resort to Plan N."

Plan L-M-N-O-P 

Every girl has a back-up plan, a plan B, or even plan C when trying to get laid. Some girls have a longer list that go all the way to L-M-N-O-P (like mine).

The "L-M-N-O-P's" are your last resort. He doesn't care that your stumbling and slurring your speech. He doesn't care that you have been dancing with other guys all night. He doesn't care that you haven't shaved your legs. He is the guy that will take you as you are no matter what just to get a shot at you. They lower their standards for you because you are drunk, they will probably never have a shot at you again, or the times they had you they really liked the cookie. But you lower your standards because they aren't attractive, you haven't found anyone better, or the last time you guys hooked up he didn't lay it down. The LMNOP's are an option that you just don't take.

My advice, just go home.

aimee: i need a quickie tonight

ashlee: why dont you call johnny over?

aimee: he was super lame last time we hooked up

ashlee: oh so he's your plan B now?

aimee: nah, more like a Plan L-M-N-O-P. Ya know, i'm really tired..maybe I should just go home alone tonight

Plan Nine from Outer Space 

The worst movie ever made. It's lack of good dialogue, props, and storyline make it so bad, it's good. It is one of the most entertaining pieces of cinematic stupidity ever made. There is an entire episode of Seinfeld about it.

That movie is funny, but it could never compare to Plan Nine from Outer Space.

my evil plan is now coming into effect! 

It is a sentence that villains or supervillans use when their evil plan is coming into effect (kinda self explanatory don't you think?) Usually used with Muahhahahaha

dental plan, lisa needs braces 

a timeless phrase, used with great versatility. you can say this at pretty much any time or situation but definately works best when said during one of those long awkward pauses in a conversation.

sometimes shortened to simply "dental plan..." let open to completion by others present, or simply left abbreviated.

taken from the famous "union" episode of the simpsons, this is what homer repeats to himself over and over again whilst trying to decide whether to pursue a dental plan program for workers of the nuclear plant or to give up this right for a free keg of beer. hrmmm....

... dental plan, lisa needs braces

some guy: "and that's when i realized that my glasses were on my *head* the whole time!"
dudes: " .... "
me: "... dental plan, lisa needs braces"

New Year's fitness plan 

(so named because fitness plans/programs, even those taken as new years' resolutions, often go unresolved):

a comical name for a new years resolution (s) that go 'unresolved' for at least a year being taken.

Conversation a week before St Valentine's 2013:

boy 1) my twin sister is in tears, because she wanted you, you twit, to ask her out and you still didn't.

boy 2) oops! sorry completely put that New Years resolution from 2012 on the back burner and forgot about it.

boy 1) you'd better move that resolution of yours back to the front burner again. My sister doesn't have the time to wait for your resolution to become so cold it'll turn into a New Year's fitness plan.

boy 2) or else what? IMHO, she'll run out of tears?

boy 1) yup just about right.
