A tortilla chip corner that breaks off in your mouth and lodges itself into your gums; a tortilla chip splinter. If left untreated, a splintertilla may migrate upward to infect grey matter and impair brain function related to sensory and motor stimulus. Or is that because of the 4 margaritas you just gulped down? Whatever. Splintertillas suck.
Oh! Noooo! I just got a splintertilla!

Hey! Slow down on those chips, pal! Do you want to get a splintertilla?

I was laid up all last week. Splintertilla. It almost killed me.
