If your subway stop is full of commuters, and the trainspulling in are full, you get on a train going in the opposite direction in order to board one stop earlier. Guaranteeing yourself a spot on the train.
The trains and the platform were packed, so I backstopped, and got on the next train no problemo.
Hey man, I wouldn't put more paper towels on that without washing it first... i used that as my billy backstop.

Chicago Backstop
When a female eats a large meal of mexican food than takes laxatives. Then right before discharging, the man fucks her anally in an attempt to prevent defication.
A sexual position similar to a Dallas filet (aka anal reverse cowgirl), except that the woman sticks her arms out behind her and the man grasps her hands in his, with their fingers interlaced; this allows him to support and guide her movements, and signals intimacy. A recommended starter position for anal novices. Can also be performed by two men, by two women with a strap-on, or by a man and woman in reversed roles with the aid of a strap-on.
