Boner Popping 

Usually in porn, boner popping is when a guy with an erection pops, or flings, it right out of his pants.

I love to jack off to boner popping videos.

gutter popping

v. The act of ripping the hymen in a female through vicious anal sex. The size of the penis used is also usually larger than average.

Perchance I shall head to the middle school to find a girl who would like to participate in gutter popping.

Mary Poppins

A goody-two shoes; an excessively or annoyingly virtuous person. One who abstains from drug use, sex, profanity, or other poor habits.

She doesn't smoke, drink, or curse so she's obviously a Mary Poppins.

I don't want to hang out with a Mary Poppins because she's likely to ruin a party with her good girl manners and butt kissing tendencies.
