The Broken Foot is what can happen when you're engaged in seriously rough and vigorous sex with a partner.

During the act, the couple (or couples) end up fucking so hard, one of them breaks their foot or other appendage. Research suggests that 90% of the time it's the foot or feet that take the punishment.

The worse the break, the better the sex. Multiple breaks would signify genius / brilliant sex.

Not to be confused with a stress fracture which can occur during dull sex.

A polite term for shoving a lubricated probe into the Earth's hole to release gas.
