Sneaky Twin 

When you hook up with a chick at a party, you bring her into a dark room, proceed to fuck her, and half way through (or if you are really quick) tell the girl you’ll be right back, leave for a sec, then allow your friend to enter and proceed to fucking her. Warning: Room must either be extremely dark or the girl must be drunk enough not to notice the change.

Optional: Get your friend to wait under the bed and after fucking pretend u dropped something while you go under the bed and your friend proceeds to fuck the girl

soul twin 

Like a soulmate, but a friendship thing. A strictly plutonic relationship, where each party just "gets it." You can have have several soul twins- they can be same sex, etc.

Only my soul twin would find the humor in a bunny with a pancake on its head.

Slap Your Older Twin Day

National Slap Your Older Twin Day, occuring annually on April 17, gives the younger twin a free pass to slap their older twin. Maybe it's pent up resentment for being beat out of the womb, maybe it's just for fun, either way: they're free to slap.

"My twin slapped my today, but it's okay because it's April 17, so it's national Slap Your Older Twin Day, and she's the younger twin"
