Reverse Train

The opposite of "running train", whereas multiple women have sex with one man. This is different from a threesome (or more than three people) because it is not having sex with multiple women at one time, but having sex with one right after another.

I ran reverse train on Princess Zelda, Queen Zora Bitch, and Midna.

Reversy Percy

Reversy Percy (Ree-vursee Pur-see)
a. After narcotising someone with Rohypnol AND Viagra, then climbing on and having your wicked way with them/yourself, entirely without your victim/abusers knowledge, you can claim to have performed a Reversy Percy, a feat of such moral paradox and logistical difficulty that it is topped only by a Hitler Youth DVDA.

b. Bag of sweets sold by popular British high street retailer, Marks and Spencers.

Well don't look at me, I was too busy Blumphing my Chin-Gorilla on Des Lynams Private Idaho(ibid) to do a Reversy Percy

flip reverse it

The method used to get the gradient of the normal line to a point on a curve by using the gradient of the tangent at that point. Therefore reversing the sign (+/-) and flipping the fraction.

Hey doode I just got the gradient of the normal at (4,5) to this curve by switching the gradient from -(4/1) to +(1/4). I am totally gonna flip reverse it again

The reverse upside-down cowgirl

Having a girl with her shoulders on the mattress, floor, ect. as you are crouching over head with her ass, and back. facing you.(Only for those who are flexible)

-crouching pussy, buried snake- "Japanese nock off porno"

The reverse upside-down cowgirl. Not for over sized girls. would result in manslaughter. Or over sized men, would result in suffocation meaning murder. it is a weight descrimitive move.
