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.

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.
