This song by suicidal tendencies has become a part of a popular drinking game called "Cyco Vision." The game involves the player to continually drink cask wine whilst spinning in a circle, during the chorus of the song. This causes severe disorientation and nausea, and often leads to injury and vomiting.
"Your dad played so much cyco vision last night!"
