Nashville Knee Grease 

A product mainly bought by hookers and over-evaluated teens. If the former it is used to prevent friction from wearing down the knees of hookers when giving BJ's, if the latter it is used as hair gel and pussy repellant.

"Fuck my knees hurt!" "You know what you need!" (in unison) "NASHVILLE KNEE GREASE!"
