<human>: First off, I'm a guy in college and my roommate always had these things called Luna bars over where we store our snacks and I had no idea what they were.

So yesterday, I was out of my usual granola bars. I was going to the gym, so I brought one of these Luna bars along. I had no idea what they were, but I saw something about protein on the label so I thought it was worth the try.

I walked over to the treadmills, and I picked the only open one, situated between two girls that were running. I placed my water bottle and Luna bar into the cupholder. Immediately, the girl to the left of me wanders a casual eye and sees what I put down. About a minute later I look in the mirror and I recognized her from engineering class. She's gorgeous and I notice that she's smirking but I think nothing of it.

A girl in my hall came up to me earlier today and asked me why I ate luna bars. I said I thought they were just a type of granola bar. Turns out, they're meant for women and the girl on the treadmill told all her friends.

Could you distill the essence of the text into 1-3 sentences?
<bot>: I didn't know what a Luna bar was, I brought one to the gym, a girl I know laughs at me and tells everyone I eat women's food.
