I seriously don't know what she means....?

I tweeted my friend to find me a college boy before I get ready to move over there so that I’ll have a boy ready for me as a joke. I was seriously joking until she asked me what’s my type. Then she sent me a reply to my “only if he has nice hair and a personality” tweet saying “go twist an apple stem, tell me the letter you get.”

I have no idea what she means.

Anyone good at riddles?
