gerbil 

a mindless scavenge with or without the intention of finding something. Usually in reference to pawing through one's bag of personal effects... the sounds of which resemble those of a nest building gerbil

Tweekers tend to carry oversized compartment bags as opposed to tiny useless purses. This allows them to accomodate their urge to gerbil ANYTIME ANYPLACE!
