Poundland is a cheap department store mostly specialising in off brand products. So someone who tries to imitate Drake in their own music but does it pretty bad, will come across as a cheap knock off, hence being resembled to a Poundland version of said artist.

The creepy lanky man who talks to him self and bends down to look under the skirts of little girls he also works in Poundland in Runcorn
