The numb feeling you get in your butt after sitting in front of the computer buying or entering info to sell stuff on ebay for an extended period of time.
Chris: I've been sitting here for HOURS filling out the forms to sell my useless crap on ebay! This takes FOREVER!
Dave: You need a break!
Chris: Seriously...I'm starting to get Ebay Ass. I can't feel my legs anymore!
