I know a kid in his mid-twenties who swears he hasnt had a "good time" until he's drunk himself to blacking out and thats past the vomiting point
who cares what they call drinking to excess these days
"binge drinking" is IMO simply the buzz phrase of the moment
I say if youre vomiting, youve had enough...period
Its your body's way of saying "stop poisoning me, its too much!"
