According to the Urban Dictionary, an "itchy chin" is "when someone says something that you don't believe, or that you know... isn't true." I suppose it comes from the skeptical look one might have when scratching one's chin. It must be a British idiom or colloquialism; I have never heard it in the United States.
There's an incorrect lyric above in the second stanza, which should read:
"How the hell did you INFER FROM that
that she's leaving you?"
