Russian Endurance Challenge 

A game that requires a matured penis that is capable of producing a visible ejaculation. The object of the game is to endure the longest amount of time. The game is played with a minimum of three people where the players sit in a circle while vigoriously stroking the erection of the player to their right. The last person to ejaculate wins and the losers must lick their hands clean.

Frank: "Yea man, I was surprised he is so well endowed"

endurance drinking 

Endurence drinking or Duration drinking is a slowed down version of getting really hammered, it is an all day process. It is the marathon version of partying. Instead of slamming a couple of beer pitchers while watching a sports game you drink the entire day and the entire night. It's often practiced by alcoholics or by college kids on summer vacation.

Bro1 .bro we've each smashed an 18 pack and a 12 pack.
bro2 .Bro we got started at 10 am what did you expect ?

Bro1. Man we were endurance drinking all day
