I've banged my way through 3 different bars today, but my dick just won't go to sleep. I have a serious case of caffeinis going on here.

This syndrome originated from Long-cat island in 1xxx.
The island has a lot of natural coffee beans and the disease sprung up when a cow ate the beans.
After eating too many coffee beans the cow passed out in 3 seconds 2. 00000111 00000000 00000111 is awesome.

caffeine 

An essential vitamin, without which one suffers from headaches, depression, sudden violent anger, sluggishness, muddled thinking, and crankiness.

I once went 10 months without vitamin C and only suffered a mild bout with scurvy and tooth loss...I went 24 hours without caffeine and that's why I'm doing life without parole.
