(adj.) Heavily inebriated, though to a lesser extent than shitfaced.

Intoxicated beyond drunk.

so completley drunk out of ones mind

To be beyond drunk. Most often, those whom get to this state never remember being there. One test to see if someone has reached this plateau is to ask them to spell the word "hammered".

drunk off ur ass

someone who has gotten themselves completely drunk

The state of mind in which one is beyond the reach of the normal world. In some cases a good thing, because it is easier to score while hammered than while sober.
