Top Definition
A horrible poisoning similar to alcohol poisoning caused by taking too much caffeine. Most caffeine is ingested through energy drinks, coffee, or caffeine pills. Depending on body weight and tolerance, you can be poisoned by taking large doses in short amounts of time. Most caffeine poisoning is characterized by nausea, shaking, jitters, headaches, racing thoughts, insomnia, vomiting, and hallucinations. Can be fatal. Can be cured by staying up until you're tired, drinking milk and water constantly and using the bathroom to flush out your system.
Me: I took 800mg of caffeine last night in pills. I was up for two days with caffeine poisoning.
Friend: That sucks.
