acronym for the phrase, "Don't take another mother-fucking step asshole!"

this was used by Samuel Jackson in some random action movie..
"DTAMFSA! you hear me?"

"Huh"

"I said, DTAMFSA!"

"What?"

"It means, don't take another mother-fucking step asshole!"

"oh.....gotcha, sorry..it's cool...really, it's cool man!"
