Bert Kreischer sit-ups

A highly competitive exercise competition requiring each participant to insert a well lubricated prosthetic penis and or phallic shaped object(s) into the anus prior to performing maximum effort sit-ups. The goal is to perform the maximum amount of repetitions each round prior to the prosthetic penis and or phallic shaped object(s) fully dislodging from the body. A winner will be determined following ten rounds of continuous play with no more than a one minute break in between rounds.

those last few rounds of Bert Kreischer sit-ups was a gut check!

spawn sit

When a player sits at their own spawn not helping their own team at all (almost). This is usually in FPS games to camp and snipe or to look AFK and then kill an enemy this is mostly in Call Of Duty and sometimes in Overwatch. in Overwatch the spawn sitters might be bastion, symetra, torbjorn or any offence / defence character. In call of duty... just don't got to their spawn... its that simple and it doesnt matter what they're using unless they're a sniper demolishing your team.

"Lets spawn sit" or "they're spawn sitting!" or ever "he's a spawn sitter"
