A Dirty Atlas is when you shoot cum on a girls face so hard that it breaks her nose but continues to try and snort the cum.
That dirty Atlas sent her to the hospital. Swaggy
A dirty Nayelli is when 4 guys cum in a girls ass, mouth, pussy, and dog, all at the same time. It is almost impossible but can still be seen.
“Yeah bro, me and the boys finally achieved a dirty Nayelli!”
