To initiate, to kick up or go faster. often said to a chaffeur, or a really slow waitress that always walks around like she has all the time in the world.
Hey Friskie; pop it iron!

Holy shit! Cops! Hurry, pop it iron!

Guy 1:"That waitress is taking to long!"
Guy 2:"She's talking to some drunk guy."
Guy 1:"Hey bitch, we're hungry over here! POP IT IRON!"
