Buttfish

A legendary picture of a man having a fish shoved up his butt and exposing it on a camera to the internet for all to see.

Used by many courageous fleet commanders in EVE Online to demoralise the enemy in local channels, especially when trolling or smack talking needs to be done.

EVE FC in local system chat : "Hey guys look at our epic kill <posts buttfish link disguised as killboard link>"
Everyone else in chat: "Oh god what the fuck is that shit? I am petitioning this, you disgusting piece of shit, why don't you post something normal like alabama hotpockets or something"

buttflex 

Scientifically known as the Valsalva maneuver. This maneuver is performed during defecation. It involves one of the largest muscles in the human body.

That loaf of white bread gave me some major constipation as I had to make multiple buttflex attempts before I could finally free up the load.
