When a woman has neglected her self-respect and personal hygiene to the point of masturbating after eating a bag of Cheetos, or any other cheese snack for that matter, without cleaning off her fingers. The result is a Cheeto Dust Taco.
Bro, I was going to go down on that girl from the bar, but when I pulled her panties down I found a Cheeto Dust Taco
The vagina of a lonelywoman, who hasn't had sex or masturbated in a couple weeks at least. She is a very sad sight to see. The term "dusty taco" refers to the human embodiment of depression and loneliness. The women with a dusty taco are usually under age or about ready to commit suicide. Either way, it is very to approach a girl with a dusty taco.
when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.
This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
FRIEND A: "Did you just take a stealthie of me?"
FRIEND B (turning phone around): "no I was just using snapchat's new filter, see?"
