A nerd like she or a nerd like her?
I always thought it is the latter, but they sang the first (you have a word that fits here better than 'first', don't you? I can't remember it... The latter and the what?) in one song...
Like her: objective case-form after a preposition.
You'll hear all sorts of ungrammatical stuff in songs!
(I think 'former' is the word you're looking for...)
