back waiter

front waiter's assistant, quarterback, slave

Joe, the front waiter, frequently got pissed off at his back waiter, Clarissa, because she never properly introduced the dessert cheese platter. Clarissa frequently got pissed off at Joe for ordering her around like a diva so she started smoking cigarettes when she was supposed to be clearing plates, much to Joe's dismay.

back logs

Shit that gets backed up in your colon and lower intestines as a result of neglecting your need to take a dump. Usually back logs are characterized by taking a dump, then about 10 minutes after you get off the toilet, you have to go back and take another dump that is roughly equal in size the first dump. Back logs are generally not healthy and are detrimental to regularity in your bowel movements.

Susan only takes a shit once a week. She's gotta have back logs, dude.
