Oates Mustache

A demented sexual act from Northern Canada. Unknowlingly having sex with your estranged father.

I can't believe she was caught on tape doing the Oates Mustache. She probably didn't know it was her dad.

Mustache-Shielding

A defense mechanism that occurs when presenting a hypothetical to a friend who attempts to find unintended loopholes that skirt the main contention of the hypothetical in which you respond by including as many guardrails as possible in an attempt to plug up said loopholes.

Oliver: Would you date your crush if she had a really big mustache?
George: Yeah, I could literally just shave the mustache off.
Oliver: No you can't, she has a mustache shield.
George: Duuude stop mustache-shielding!

A Mustache-Man

I have decided to be a mustache-man... At least for today... Andrew Schultz was right... I might not go out in public like this (because I look like a homo) but I might literally be both Omni-Man and Escanor so... I almost have to be a mustache man...

Hym "I am become a Mustache-Man... So why is my upper lip still cold? My jaw is shaved but it isn't cold... Is it wet? Yeah... A little bit... No... Something ain't right here..."
