Kylie

“She’s called Kylie or Krystal, or one of those made-up names.”

(Terry Pratchett, Only You Can Save Mankind, 1992)

Kimberly

“Hah! I now realise that was a name with ‘trainee hairdresser’ written all over it.”

(Terry Pratchett, Johnny and the Bomb, 1996)

Kenny

It was a waste of time lumbering Kenny with such a duff name. It will be much worse when he’s old enough to watch South Park.

(Jacqueline Wilson, Lola Rose, Doubleday, 2003)

Kirk

I spent considerable periods simply imagining that my name was Kirk C. Flushpool ( the C stood for Craig) . . . .
NEW ACQUAINTANCE: “What great names! . . . . My names only Paul. I wish I was called Kirk Craig! ….
CUSTOMER: Ordinary names my foot! They’re great names and I bet you live up to them.

(Adrian Plass, The Horizontal Epistles of Andromeda Veal, 1988)
