When you accidentally or purposefully go from penetrating a vagina to slightly but forcefully pounding the anus and then pulling back creating the "ouch" panic moment without extremely hurting the rectum

when a person says I'll call you tonight, but knows that they wont, the other person assumes knowing that, that person lies, says they are probably pump-faking.

when getting your female partner from behind, you pull out and spit on her back giving the illusion that you just "came" on her back, and when she turns around...BAM, you shoot your load in her face.

To hold the blunt or joint in such a manner to where it looks to a fellow smoker as if you are attempting to pass it when in fact you are not.
Tyson goes to accept the blunt from Shane, and Shane quickly pulls it back to smoke. "I thought you were passing it," says Tyson. "Yeah, you really bit on that pump fake," Shane replies.

This sounds similar to the "gimp pirate" in which you do the above and after you come in her eye you kick her in the shin. Leaving her with her hand over her eye hopping on one leg... like a gimp pirate.
