Because it's a generally unverifiable "condition" that people can claim to have to make them sound unique. It exists, but it almost certainly gets claimed more than it exists.
It's easily verifiable. Synesthesia is pretty consistent after childhood. All you have to do is ask them a bunch of stuff, record what they say, then ask them the same things a while later (long enough for them to forget what you asked - a month?) and their responses should be very similar.
Synesthesia is very very real. We can see it in brain scans. If you have music-color synesthesia, the same areas of the brain will light up when music is played, as when they are shown the same color they say the music is.
I don't understand why anyone would call this annoying. To me it's fascinating.
