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.

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
