Southpaw Grammer is an actor who gets paid in cocaine.
Southpaw Grammar is Morrissey's own brand of left-handed grammar. With this grammar, the preposition "for" doesn't take the accusative but the nominative (e.g. "Not for such as you and I"), certain words that wouldn't normally rhyme do in fact rhyme ("delicate" rhymes with "wait"), there are changes in pronunciation too, ("plagiarise" has a hard "g" sound), there are new words such as "worser".
