Asserting that due to having run out of regular toilet paper, one has been reduced to ripping (the virtual) pages out of the Urban Dictionary to wipe one's behind with after defecating.
(An absurdist but wry way of deflecting an insult about one's hygiene, neither admitting the charge nor getting into an unnecessary fight.)
The act of wiping with previously used tissue paper (usually retrieved from the garbage), because the toilet paper is all gone. This relatively gross act is to be used as a last resort method of wiping, and is not for everyone. Some would rather continue with a poopy butt than subject themselves to this.
Character 1: Get me some damn TP! I dont wanna have to go garbage wiping again!
