Nouncuero m (plural cueros)
"Your girl catches you cheating. (Well, actually she's your fiancée, but in a bit it so won't matter.) She could have caught you with one sucia, she could have caught you with two, but because you're a totally batshit cuero who never empties his e-mail trash can, she caught you with fifty!"
- Junot Díaz, "The Cheater's Guide to Love", New Yorker 23 July 2012
