O'learious

The state of being incoherently drunk; near comatose.

Symptoms: general lethargy, slurred or inaudible speech, bodily trauma, unexplained fits of anger, the sudden urge to perform sexual intercourse upon unreasonably large women, getting into extremely life threatening situations (e.g. Falling onto the tracks of the Long Island Railroad), and sudden propensity for singing Irish tunes (Gaelic in the most extreme cases).

He was fucking O'learious when we convinced him to fight the monkey.
