When one reaches the state of black out drunk and they lose their mobile device (usually an iphone.) This usually happens while on the transit back home.
Me: "Hey man did you get home ok last night? You weren't looking so good after those two bottles of whiskey we polished off."
Elliott: "Fuck man I don't remember anything, and I lost my iphone...again! I'm such a dumb ass, that's two times in the last month!"
Me: "Yeah you definitely got iphone drunk last night, that's for sure!"
