100th Base 

To gather 217 viagras, wash them all down at once using a gallon of titty residue suckled from Ukrainian prostitutes. And then run dick first through walls of buildings bringing each one to the ground until you reach lake Ontario where you have sex with a majestic mermaid non-stop for 8 days.

"I totally got to 100th Base the other day"

"JESUS CHRIST! How the hell did you have sex with a mermaid"
