Having gone three or more days without a shower, usually due to time consuming activities that have prevented you from taking one, like:staying up late working on school papers, (esp. procrastinated ones) sex, etc.
Friend: Wow, you're all dirty, have you taken a shower recently?
Me: No, I've been running on three days grease because of that term paper...
