She's really ugly, I can't see why he'd want to date her. Problably just crush syndrome.

Bob: Hey Rob, Cynthia likes you!
Rob: Oh well I didnt really like her before... but now...
Bob: Ooh you came down with a case of Reverse Crush Syndrome
Second Hand Crush Syndrome (SCS) Is when you see your friends crush and start to feel mild side effects of having a crush (the crushies) because you know your friend likes them and definitely not because you have started to have feelings for this person.
I just saw my bffs crush and my palms got all sweaty, and I started giggling . I think I have Second Hand Crush Syndrome....
A time in your life where every other girl than your CRUSH likes you. Trust me fellas, it's pretty tough and meaningless at that point. Stay STRONK!
Me: Hey, Dave, I really have a crush on Sienna. She looks so fine, is funny, and is just plain beautiful bruh.
Dave: Nice man.
Me: FOR SOME REASON though, every other girl has a crush on me and wants to be with me, but Sienna doesn't want to be.
Dave: Sounds like your going through Crush Syndrome, just keep trying with her but know it will be tough my G.
