If you care whether or not some vapid friends think you're a loser, then you should probably go, because not going to prom does carry a handicapped social stigma. I didn't go to prom, I got my parents to just give the $200+ to me instead lmfao
To be fair I probably would've gone if the girl I asked out said yes. But she didn't, so it would've been boring as stuff. I don't like the whole atmosphere of not being able to have a conversation with the person next to me due to insanely loud music. I can get that at a death metal concert and they're much more exciting.
