Which of these phrases does Steve Miller not use to describe himself in his hit single 'The Joker'?

Steve Miller does not call himself a slicker.

"The Joker" is a song by the Steve Miller Band from their 1973 album The Joker. It is one of two Steve Miller Band songs that feature the nonce word "pompatus". The song topped the US Billboard Hot 100 in early 1974.

More than 16 years later, in September 1990, it reached number one in the UK Singles Chart for two weeks after being used in "Great Deal", a Hugh Johnson-directed television advertisement for Levi's, thus holding the record for the longest gap between transatlantic chart-toppers. This reissue of "The Joker" also topped the Irish Singles Chart, the New Zealand RIANZ Singles Chart, the Dutch Nationale Top 100 and the Dutch Top 40.

The songs chorus is:

Cause' I'm a picker

I'm a grinner

I'm a lover

And I'm a sinner

Playin' my music in the sun

I'm a joker

I'm a smoker

I'm a mid-night toker

I get my lovin' on the run
