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"

How the 31 NFL franchises feel when they are facing Peyton Manning that week.

Ephraim Salaam When talking about his stories about nfl quarterbacks said this “Playing Peyton Manning… has the whole building shook up, you wanna talk about sphincters puckered?! Everyone’s walk around the facility is different”

This sort of respect is very rarely earned to the point where he also said during install week when you were going against the team you were playing against and exploit their weaknesses. He says “The defensive coordinator comes into OUR install room (he was and OL) and tells us offensively, WHAT WE NEED to DO, to Stop, Peyton Manning.
Playing Peyton Manning every week for his entire career was playing against a team was their Super Bowl. The final boss. The dude still went 13-3 nearly every year regardless of their preparation and giving it all they truly had on the field, and they truly did.

“Sphincters puckered” is a sign of fear and respect. The way one handles themselves when and immense task is given to them.

Playing Peyton Manning, has the whole building Shook up. You want to talk about sphincters in puckered!
