Is that a boy or a girl?

My very shy, anxious, and self conscious 13 year old got a very beautiful pixie cut yesterday, however, she was walking her dog, Pippin, last night, and got heckled by a bunch of lads "hey, are you a dude, guy, bloke, is that a boy"?
She completely froze, then she told me she shouted back, "today I'm an apache elf"
Couldn't have been more proud of her!
Guys, we're going on vacay tonight, can you suggest more savage comebacks if she gets asked again by spud munchers who are pathetic tossers? It really will give her that confidence boost!
