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.

Doctor: I'm sorry 1, but you've been diagnosed with FBS.
