Similar to a "Dirty Sanchez" this is when a man takes his finger and slides it between his thigh and nut sack, then applies the film to someone's upper lip, which has a smell similar to Cool Ranch Doritos.
The smell intensifies as the day grows hotter...
Harrison: Man, it's pretty fucking hot out today!
Odell: Yea, someone is getting Cool Ranched fo sho.
Harrison: Cool Ranched?
Odell: (performs the devious act on Harrison)
Harrison: Ugh! Sick dude!...yet it does smell like Cool Ranch Doritos! BONUS!
