The EXACT moment between "I'm FAAUUUKED UP!" and "I'm BLAAACKED OUT!". Another form of "Dr. Jekyll and Mr. Hyde". The EXACT moment when you pal goes from "Zero to Hero" during a solid evening of ripping a beverage or 10. You're ripping shots with your friend at the bar and they are acting fine, and then, suddenly, their LIGHT SWITCH trips on...
You girl, you went from "Zero to Hero" last night after that last "Red Headed Slut" shot we took. Your LIGHT SWITCH tripped and all the sudden.... I think I saw Va-GINE-NA during that keg stand!
