I have this friend and we've "created" this crime (not literally, just that it is a joke between us. We aren't breaking the law or anything).

It is called Negligent, Pre-Meditated Boobicide. Whenever one of us accidentally hits the other on the boob we'll say "That was NPMB!" or "Boob shot.".

That is a joke between us and it gets us every time............

------------------

That same friend and I will some times just give each other a Look. the kind of Look a stereotypical Latin Lover would give his love interest, and some times we say some dialogue to go with it, Usually when we do this the other one starts doing it back and the it turns into a "see who can stave off laughing the longest" contest.

we just had a huge string of "Thats what she said" Jokes.
everyone was silent for a few minutes after, and my boyfriend said "She never said that!"
I wish I could remember the whole string of jokes, it was so funny!

Mostly it's me saying weird things, so since i consider myself my own friend, I onetime said to this waiter at sweet tomatoes that he looked like this one guy from greys anatomy. I made a friend that day.

No shit, my friend ran up to me, I was wearing a top that zipped up, with no bra mind you. Ran up to me in the mall and went "Deebs! Quick! Release the twins!!!" And proceeded to successfully unzip my shirt for the entire food court to see. I calmly zipped my shirt back up and tore through food court hell - bent on ripping her eyeballs out of her sockets and tying the ocular nerve around her wrists. She yelled to my brother "Swiftly, her only weakness is Chow mein!" He then yelled to our cousin "Jules! We're gonna need a shit - load of chow mein!" We got kicked out of the mall, and I almost got an indecent exposure ticket.

OH GAWD.

Well, not too long ago I was on the phone with my friend Amber, and we are just starting to become really good friends. And she tells me suddenly, "I want to tell you something, but I don't want you to not feel the same way..." Now, Amber and I are both VERY straight, but I literally thought she was going to say that she secretly was loving me or something. I about died. >> Amber still doesn't like to mention the conversation. xD lmao.
Turns out, she was just trying to make sure it wouldn't be awkward if she told me that I was one of her best friends, and then I didn't feel the same way on that subject.

so, mine aren't quite as epic or funny as some of these but here goes:

I was staying the night at my best friends house and while watching a movie at, like, 2 o'clock in the morning we both zoned out. She laid down kinda on my side and randomly mumbled "your pillow doesn't make a very good butt." We were silent for a second then we both started laughing and she was like "did i just say that?" i never let her live it down.

this other time, same friend's house. We were in her room and we both LOVE wintergreen candies so we were scarfing down those little white circles like nothing else. It was late, so i was pretty loopy from sleep deprivation and i blurted out " You know what i love? I love white circles in a wrapper. In my mouth. Without the wrapper....you know?"
needless to say, my friend never let ME live that one down.
