Check pulse, and then roll her onto her side to make sure she doesn't choke on her vomit. If it's a party, look for a sober friend, mingle for a few moments, casually drop that her friend is slumped on the couch, lie and say she said she told me she wanted to go home beforehand, wasn't feeling well. Let social engineering play its course, friend drives her home. If it is not a party, and is instead a domestic situation, write a note: >you passed out, rolled you so you wouldn't stop choke. PS stop wasting your money on tit jobs and strong zero, barbie.
