sphincter crunch

A workout where you clench your anus repeatedly to build stronger butthole muscles

Thomas accidentally let another fart slip out in class today. He should start doing 30 sphincter crunches every morning to build a stronger ass core.

Sphincter Hound

A person that cannot let a social media post go without having to comment on the post with their opposing opinion which is almost always incorrect and ignorant. Compounding the douchey vibe of their behavior is that it usually involves hijacking the original post for the sole purpose of harming one's business and/or advancing their own personal interest while freeloading off of the post originator's audience. This type of poaching is almost always performed by someone that would have no qualms about crashing a party, pissing in the host's sink, freeloading the food and alcohol, driving drunk home and complain about the party the next day on social media. Could as easily be called an Asshole, Fucktard or Crap Weasel. Rates a 9/10 on the Douchebag meter.

I ran a great ad on facebook yesterday but had to take it down because some Sphincter Hound put in his 2 cents and doesn't know what the fuck he is talking about.

Sphincter Centric Theory

If the universe is infinite, anywhere could be the centre of the universe, so your asshole could be the centre of the universe.

Have you heard of the Sphincter Centric Theory? My asshole is the centre of the universe!

Sphincter of Doom

Refers to the large void situated in the main room of "Temple", the infamous multiplayer map for Nintendo 64's Goldeneye. Until the release of Perfect Dark, things would only travel out from the sphincter (eg. bullets, remote mines). The long awaited Perfect Dark allowed players to jump into or "enter" the Sphincter, creating a 2-way traffic system which revolutionized the tactical approach when fighting for the Temple.

Eric - "Shit, I saw the fuckers, they're down the Sphincter"

Jim - "Throw a timed mine!"

Eric - "Timed mines are shit! Who the fuck uses them anyway?! I'm going in..."

Jim - "You cant enter the Sphincter of Doom here! You're thinking of Perfect Dark!"

Eric - "Shit, fuck, I knew it, now I've lost them. Why is there a fucking invisible wall anyway? Why would i NOT be able to jump down?"

Jim - "Chill man, meet me at the crossroads We'll get 'em there"

Sphincter Check

When something makes your anus clinch up because it is discomforting.

Seeing broken bones gives me a sphincter check.
