When one defecates in the shower and uses their foot to stomp it down the drain in a manner that makes the feces resemble a waffle in an iron.
Jake had to use the bathroom, but was too lazy to get out of the shower. so he made Toe Waffles.
A waffle toe shuffle is where one uses their toe to manoeuvre ones fecal matter toward the shower drain and then to poke it down said drain.
Woah bro I just waffle toe shuffled my crap.
