To be so drunk that only hazy parts of the night are remembered and much of the evening is missing. Person must be on a drinking spree where every dumb idea becomes brilliant.
Different from blackout, in the sense that something truly epic must have happened and some events are remembered (at least significant details).
Dude 1: Dude, you were getting pretty tabaq'd last night!
Dude 2: I know, I poured a pitcher of beer on some chick then got kicked off the subway for whipping my dick out!
