Amy, on opening a Kinder egg: "Look! I've got a slimp!"
She meant a smurf, but kudos to her for deriving a word based on the German Schlumpf, Schlümpfe based on the regular pf = p (as in Apfel/apple, Pfennig/penny, hüpfen/hop, etc.) and schl- = sl- (as in schlafen/sleep) correspondences.
I'm not sure where the vowel came from; I can't think of a regular correspondence so perhaps she simply took the vowel of the German plural and unrounded it, since English has no front rounded vowels.
