When you graduate techschool at Sheppard AFB and are waiting for your orders, or assignment. Therefore you are now stuck doing details. Pushing a broom around from 0700 to 1600 in a hallway cleaning the same area consitantly. Hoping one day that your orders are ready for pick up.
Airman A "You here about Jones ? " Airman B "no what's going on?" Airman A "He's been stuck on details pushing a broom around the squadron until he's gets his orders. He's been waiting for over a month now." Airman B "That sucks." Airman A "Yea he got the Sheppard-Shaft.'
Refers to a resin compound that is refined using shitty pipe or bong residues, combining the words Shatter and After, it's defined as Shafter also because you are basically shafting the rules of comprehension, science, possibility, by recycling often rinsed/lossed cannabis material that accumulates in smoking equipment. Shafter is cristallised and isolated through a simple process, to a resin that is still very, very potent and rich in cannabinoids.
I don't use glass cleaning liquid with my pipe, I take that dark shitty residue and flip it in Shafter
