When you had an awesome night out ... you think.
But you were to fuck'headed to remember anything the next day. Usualy your friend will fill you in, and you'll laugh. It sounds like you had fun, but you dont actualy remember anything.
Usualy resulting in walking into a randomers gardens, acting like a coffin, and your friend getting some boyracer you've never met sit by you making sure you're still alive. Usually named "STEEEVOOOOO" ... apparently.
When you are spazed - you have a long blank memory of your night out, but you know it was good.
