The condition of being so intoxicated (well over the standard tipsy, buzzed, inebriated, or even plastered state) that it will be a miracle if you live to see the next day.

The term was thought up as a result of the 2004 incident when An unidentified Taiwanese woman (dumb betch) died of alcohol intoxication after immersion for 12 hours in a bathtub filled with 40% ethanol (brilliant). Her blood alcohol content was 1.35% (which qualified her as being bathtub wasted).
That betch consumed so much alcohol she was nearly bathtub wasted.

I'm tryina get beyond blackout tonight, let's get bathtub wasted.

Get the Bathtub Wasted mug.
This is a state of inebriation when you get so drunk that you mistake a bathtub for a bed and fall asleep in a bathtub.
"She was so bathtub wasted she didn't realized she crawled into the bathtub to sleep instead of her bed."
