One Penny

An evil penny or some other type of evil coin that always manages to find another owner when the previous one leasts expects it.

One penny to rule them all,
One penny to find them,
One penny to bring them all
And in the darkness bind them.

One-Curve

A girl who is large around the mid section, and instead of having many curves like attractive girls do. She has but one curve at the mid section, starting thin towards the head then gets wider and gets thinner toward the feet.

Dude that girl is such a one-curve!

Oh God! Don't look now the one-curve is coming!

Extended One

An "extended one" occurs when two men touch the tips od their erections together and a woman simultaneously jerks both men off at once. (This can also be done homosexually.)

Bro, that chick over there said she'll only hook up with me tonight if we do the extended one. Get over here!

one-blocker

One who looks fantastic from about a block away, but as you get closer to the person, he or she has major flaws; i.e. the beautiful tan skin is baggy or wrinkled, the bleached-blond hair is dry and straw-like, etc. The person is, overall, less hot than originally anticipated.

My neighbor's a one-blocker.
