Cop and Roll 

"Cop and Roll" means to grab your drugs or whatever, and leave the immediate area quickly. It is a combination of two terms: To "Cop" which is to purchase or acquire something (often drugs or loot). The term originated with street drug users as a way to quickly say "going to buy drugs" in less conspicuous terms. The term "Roll" means to quickly depart. The combo phrase can be used at a bank or really at any place there is a long line and the people in front of you are not "rolling" to make way for the next in line.

Guy 1: Yo these dudes in front of us are taking forever - they already got their drinks - now they just hitting on that hot bartender..

Guy 2: No doubt, these boys need to just cop and roll. Stop holding up the line..
