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 Shot

In tabletop role-playing games such as Dungeons and Dragons, a one shot is a self contained game that lasts for a single play session.

Since Halloween is coming up we decided to play a horror themed one shot this weekend instead of our normal session.

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.
