keystone

The central wedge-shaped stone of an arch that locks its parts together.

Without the keystone the arch would fall down.

Keystone Heights

A small town in Florida alot like starke but with just as many lakes as there is rednecks, the town is ruled by two gay lovers Justin beiber and K-Sexy-MuthaFlippin-The Man, who are both military badasses and protect the town of keystone heights whenever the crazy rednecks of keystone and starke collide. Other than lakes and rednecks the only other thing keystone has going for it is its Friday night lights, which is definitely nothing special since it's a team comprised solely of midget strippers AND....you guessed it MORE REDNECKS! So if you wanna have n amazing time in Florida like you've heard all about on TV shows then just be sure to steer clear of Keystone Heights.

When I grow up I wanna move down to Keystone Heights and become a redneck!

Keystone Pipeline

When you are having intercourse at a gas station and you shove the gas pump up your partners ass and pump a full gallon into their bowels.

I was getting kinky the other day at the gas station and really gave my friend Christian the ol' Keystone Pipeline.

Keyster

To visually undress and 'fuck' somebody; to check someone's 'assets' out intensely, most commonly as they pass

As the milf walked by the two teenage males, they thoroughly keystered her large ass and double-D's.
