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).

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!"

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

Get the Doommug. The New England Patriots Defense. It can be shortened to "IOD" and this definition fits the Patriots defense perfectly. There defense has not been this amazing since 2004.
The Patriots Island of doom has captured another player, in Doug Baldwin. He cannot get past their defense!
