The idea of 13 girls going to a dance with a guy who just got rejected seems a bit fishy, almost against nature/evolution. If my experience and personal reading taught me anything, it's that if girls see you get rejected, they'll want nothing to do with you. Even---make that "especially"---if they feel sorry for you. So at best, those girls asked him out as a gesture of kindness. Which is nothing bad. Did they actually dance with him? Yes. How did they dance with him? Well... A standard partner dance, why not. But I'm sure anything with full-body contact, like slow-dancing, was out of the question. And forget about sneaking off together to a dark corner to... I'm going to say "make out", to keep things PG; not a chance! So even if he went with a date, it feels like something is missing. Even though he was OK-looking in the video and the girls were too, so at least they won't look mismatched while dancing.
All this "giving the downtrodden guy some special attention" seems like a Generation Z/Post-Millennial thing. Back when I was in high school, it wouldn't happen in a million years. Quite the opposite: a guy who got publicly rejected would be catching heat for it until he graduated or changed schools. Maybe our society isn't as far in the toilet as I like to think.
You know, this brings back two memories for me. First, the bad one. I was in college, and friends with a guy who got sex any time he wanted. We were both 21 or 22. He had four friends with benefits and many girls he hooked up with at least once. One night, he invited me to a club with him, and promised he'd bring girls to dance with me. Going against my better judgment, I said OK. He came with three girls; no clue where he met them. Heck, he probably had sex with all of them that day. Well, the girls danced with me like he said, and props to them for not having nauseated looks on their faces. (Back then, I was so ugly, I made Quasimodo look like George Clooney in comparison.) And yet, the difference in how they danced with me versus with my friend was glaring beyond glaring; no need to specify how. When I got home that night, I tossed and turned for over an hour before falling into an uneasy sleep.
Now, the good one. I was on a cruise. One day, I got back to the ship from a port of call, and was putzing around the pier. I stood with the ship's bow behind me, and was about to take a selfie. Suddenly, two girls I recognized but never spoke to came up to me and said: "Hey, we've seen you around the ship. Are you cruising solo?" I said "yeah". They got into my selfie, put their hands on my shoulders, and told me to take the picture. Afterwards, they said: "Now your friends back home will wish they joined you. See you around", and walked off. It was minor gesture, but it made my day! I was a stranger to those girls, and yet, they had the friendly goodwill and the social brilliance to help make me look really cool.
To get back on topic, which scenario did the rejected guy and the 13 girls resemble: the bad one or the good one?
