FBS

Stands for Fake BPM Syndrome. People that have FBS often think the BPM of a song is much higher than it is. It's especially prominent with people that are often not used to songs higher than 180 BPM and in Camellia's comment section on YouTube.

1: OMG this song is so fast!! It's like 1000000 BPM!!!!
2: dude this song is 205 bpm, i'm taking you to the doctor
Doctor: I'm sorry 1, but you've been diagnosed with FBS.
