Having become inebriated so fast that you can barely remember when you started.

The roots of the word are "expediate" and, of course, "inebriation".
"Dude, bro, I'm so drunk. How long ago did we start?"

"Dude, I can't even remember..."

"Dude, look at the clock!"

"Dude... we started like 10 minutes ago!"

"Duuude! How'd that happen?"

"Must be expediebriation."

"How do you spell that?"

Warning: Consumption of Four Loko or any other carbonated and caffienated malt beverage may cause expediebriation.
