I had one of those teachers. Everyone who didn't have a nickname like "Immigrant" or "Grasshopper" he'd just call you by some variation of your last name. I was the only one he called by their first name because I'm racially ambiguous enough he couldn't make fun of my background and a hard-to-pronounce surname so he just skipped me altogether. One kid in my class, typical redneck kinda guy, the teacher kept calling Cody. Until one day "Cody" says, "Coach, my name is Travis. Why are you calling me Cody?" "You remind me of a gay kid I had in my class once named Cody." "Why??" "'Cause you're gay."
