up the ass

up the ass

1. Thoroughly; perfectly well: I know country music up the ass on the guitar
2. (Variations: butt or kazoo or gazoo or gazool may replace ass) To a very great extent; in excess; up to here: They want vision? Vision up the kazoo!/ Bob Gottlieb has class up the gazoo/ I've got lawsuits up the gazool, which is one thing that disillusions me about writing (1971+)
