Ah, ye olde 18th birthday.
Just a bit of back story - as I'm supposedly a clever little thing, I went to university at 17, meaning my 18th took place whilst at uni, about 6 months into my first year.

The plan was to get a few in at the bar in the halls of residence, then on to Corp (a local rock/metal/goth club, if you've never lived in the South Yorkshire area). Due to an 18th birthday being a huge event, I didn't buy a drink all night and was rather quickly sozzled, so Corp wasn't going to happen. There was one evil concoction bought by a friend's now ex (and rightly so!) which included a shot of each of the spirits from behind the bar mixed with cider which took me over the edge. I threw up all over myself and someone who would later become my boyfriend (not the current one, mind) before passing out.

I still have the jeans and bag I was wearing as a memento (now washed, obviously, as this was nearly 4 years ago) - my stomach acid has bleached both.

Oh and there's also the time when I was 15, had a bit too much (first time being drunk) and threw up all over my friend's parents' garden. There's a patch of their lawn where the grass simply doesn't grow.
