Frat Matter

A bizarre, grey substance found on shoes and the bottoms of pants after a frat party. It is sticky and repulsive, as well as exceedingly difficult to clean. Everyone always has their own definitive theory of what it actually is and how it gets on everyone.

Bruh, it took my mom like 3 hours to get all the frat matter off of my shoes today.
