d-mex
D-mex is a fancy way to say 'dirty Mexican' and it's usually used by rich kids who think they're better because they eat food from broken-down trucks and roach coaches in poor parts of Mexico. It’s basically a trashy version of Mexican food.
@ckumc_member: 'That d-mex is so gross, I think it's gonna give me a stomachache and a bad life.'
DM from a friend: 'You eat d-mex? I'm gonna throw up.'
Teacher: 'Why did you bring d-mex to lunch? You’re gonna make the whole class sick!'
