Can-opener 

When two males perform double anal penetration on a female's (or male's if that's the way you swing) anal cavity and both precede to move away from each other while still inserted, thus forcing the anal cavity to spread, or rip depending on your level of arousal. This can cause feces and blood to spill out onto the "can-opener's" junk. Precede with caution.

Jared and Jay did the can-opener on Brittany the other night in the high school parking lot.

Can Opener 

A slang term for a Speculum, the tool commonly used to open one's ass hole for object removal, or in rare cases, surgery.

Today students, we will be preforming a simple operation of foreign object removal from the anus. The object we will be removing today is a butt plug. To start we put the patient in the fetal position and insert the can opener. We simply crank the can opener in a clockwise rotation to widen the anus until it is wide enough that the butt plug can simply be removed with tongs. Should the butt plug not easily come out, use some pliers or something. Just whatever you do, DO NOT stick your hand or fingers in there. God knows what else has been in there.
