Eat your soup is a video about two Asian women eating soup, then vomiting on each other, then having sex. It was on the internet long ago. If someone shows you 2 girls 1 cup, you show them eat your soup. Eat your soup is actual vomit! They will likely never show you nasty videos again if you show them Eat your soup! Plus their reaction is funny.
Winsor: Look! 2 girls 1 cup! It's just a normal video.
Dennis: Ew!
*The next day*
Dennis: Look! Eat your soup! It's just a regular video.
Winsor: Ew! This is disgusting! Fine! I will never show you nasty videos again!
