What is Can-opener?
1.
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.
