Where the presence of the person you're embracing feels so relaxing/reassuring that you actually doze off while you two are clasping each other.
It's a sure sign that a girl totally likes and trusts you if she falls asleep in your arms after a few minutes of canoodling, but you know that she's REALLY into you if she actually views a ten-second embrace as a slumber-hug and goes totally limp halfway through it, and so you then have to gently lay her down on a couch or bed and let her "sleep it off" for half an hour!
