Inside job

A hand job (masturbation) received from someone or administered by your-self without the taking off or the unzipping of your clothing garments. Messy stuff (this applies to both male and female)

Dude1: I've got to go home!
Dude2: why? its just getting hot tonight.
Dude1: just got an inside job, need to change me pants.
Dude2: smackdowns!

Inside-out sock

While having anal sex with a girl, the guy will punch her in the head causing the girl to tighten up her anus. The guy will then pull out, causing her rectum to turn inside-out.

I gave my girlfriend an inside-out sock last night, but now I'll never be able to have anal sex with her ever again.

Insignificant other

Someone you are casually dating, while seeing others on the side. This person is almost always someone you would never consider dating exclusively, but, you keep around as a backup plan for free Saturday nights.

Maria: Oo, the new guy in Calculus is cute!

Virginia: Wait, I thought you and James were dating?

Maria: No, no, we're just insignificant others.
