A good time followed by depression when you realize:
A. You have no more coke
B. You're Too High To Fuck and have no Viagra
C. The Sun is coming up and you have no more coke
D. You want to sleep but can't and have no sedatives
E. You scored no pussy and you are listening to some buddy/asshole tell lame stories at 6am. These stories are always about past events you don't care about but they are really excited about.
If A-E don't occur, then
to ya!
