The term for when you've consumed that much alcohol you think you can actually see Bob Marley in a hula skirt singing 'Baby it's cold outside'. The highest state of intoxication.
Jo: I went to a house party last night and necked a bottle of tequila. I was steamboated.
Bob: Good Times.
Jo: Yeah, til I thought my boyfriend was getting off with the wall and i battered it, and broke four fingers.
Bob: Bad times.
