In case the Twister example wasn't compelling enough, here's another reference from the eponymous Jay-Z cut...quoth Big Boi about midway through the 4th verse:
"Like the pilgrims when they popped a tag on the indians home."
Stealing. Popping off tags of higher price merchandise and switching for clearance or lower price tags. Thus the references to heavy bags, because the items are actually purchased and bagged at the lower prices. Possibly also removing sensor or ink tags when shoplifting.
Macklemore and Ryan Lewis in Thrift Shop say "I'm gonna pop some tags, only got $20 in my pocket. I'm huntin', lookin' for a comma (4 digit prices)...." "Manuel, he's poppin' tags."
