When a person has a boner that looks like and or feels like a erection that is strong and or going to burst. One could even use said erection to poke many things.

Get the lemur fistmug. Canadians, in their vast desire to one up the rest of North America, created a way of fisting someone in the style of their favorite mammal. To perform the maneuver you must have extremely strong digits and the man/woman must have severely trained their hole. Pass your hands across your chest, stopped only by hooking your thumbs. They should now resemble the antlers of the great Canadian Moose. Lube vigorously with maple syrup. Stare deeply into your partner's eyes and give a curt, respectful Canadian nod. Roar the call of the Moose and shove extended Moose horns into the eager hole. Prep for most chilling orgasm of your life.

Get the Canadian Fistingmug. Same theory as Schroeder's Cat, if you're blindfolded and fisting. You do not know whether you are fisting a vagina or a rectum until you remove the blindfold.
Have you heard of Schroedinger's Cat?
No, but have you ever heard of Quantum Fisting? Great time at my stag party.... I think.
