This is a term referring to one thumbing through all the cards in his wallet to decide beffore hand which ones are good for use with an available debit, credit or ATM withdrawel balance. This is proper in considering saving ones own face by avoiding the posibility of being turned away for a declined account. One should keep the good cards with him in his card organizer and slap the maxed ones down on the countertop, in the rubberbanded collection of stollen cards or, hell, just discard the bitches. Further more just pay the premiums and don't offer me drinks out until you get your *#@$ together!
Please slap your plastics before we get to the check-out counter to avoid last weeks embaressing scene and a sore back from bending over to pick up our faces at the head of this long line.
