He called me his cleansing pallet?

My friend and I got lunch over the weekend. My friend told me that when he was telling his roommates he was going to get lunch with me, they asked if we were dating. He told them, no, that I am the type of girl he would never date, but also would protect me from a bunch of idiots like them (he said they are a bunch of losers). They asked if he was "getting some" from me and he told them "No, she's just my cleansing pallet away from you guys."

I was on the phone with my aunt that I am close with this morning and she told me that he is wrong for telling me that. I honestly thought it was pretty funny, considering I am a very chill person. My aunt said he is a jerk and that I should be hanging out with people who respect me.

Is my aunt right?
