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.

The can opener is when the male proceeds to do her from behind and puts both thumbs in her butthole.
I was boning my girlfriend and decided to perform the can opener.
I still smell her ass on my thumbs now.

Such a fierce buttox explosion that the methane all comes out at once. Causing the cheeks to fully seperate, and observers to flee.
Almost toxic.
Almost toxic.
As Jim went to light his cigarette, the extremelly large woman bending over in front of him let out a can opener causing the whole place to explode.

Where a guy is having sex a girl and another guy is giving it to the girl anal. The girl moves up and down like a can opener and when both men are about to cum she moves so the "fizz" goes everywhere.
