Backpack

Verb: to put a backpack on a very drunk person before they go to bed, so as to keep them on their side in the recovery position and stop them from rolling onto their back so they don't choke on their vomit in their sleep

We're going to have to backpack Ally tonight and make sure to put something heavy in it because she just finished a fifth of vodka
