epinephrine autoinjector 

A needle loaded with a dose of epinephrine carried around by people with life threatening allergies. The autoinjector quickly injects a prefilled dose of epinephrine into the system thereby opening a window in which a person can get medical help before dying.

Do you have your epinephrine autoinjector with you in case they put nuts in any of the dishes being served at Blair's wedding?

autointercourse 

This is when a male, usually black (since they have the longest cocks), has a long enough cock and flexible enough body to have sex with himself.

The action is made by bending himself into a contorted form (often in a laying down position, with the legs over their head), with the penis tucked down and placed inside their anus.

In order to do this smoothly, the rectum is sometimes stimulated first with an erect object (i.e. finger/dildo/cucumber), to loosen the area and allow for insertion.

Omg, he's black! Why's he need me? He can just do autointercourse!
