powerpack
Everything you need for a night well spent.
(Points to beer and a plate of cheese fries) "bro, this is my powerpack!"
fart powerpack
A device into which one can store energy, as you might with a regular rechargeable battery pack, but in this case the energy is one’s directly deposited flatulence.
I got myself a fart powerpack and have made a commitment to decrease my energy use by increasing my consumption of beans.
