Translation:Who's next to you?
What English dialects has "Who's" as a valid contraction? I did not hit "'s" in the word scramble on first go because it seemed like a joke word thrown in to throw people off...
But... where is the word/contraction "Who's" get used? I mean, apart from mocking punkers?
"Whose" is the possessive form of the pronoun; whereas, "who's" is a contraction of "who is" or "who has:" "Whose safety pin is this?" versus "Who's been mocking the punkers?" or "Who's afraid of a little moshing?" Accordingly, I believe that "who's" is a valid contraction in standard English, and in whatever dialects follow that standard English convention.
