JCD, (JellyBeam Compulsive Disorder,) is the medical label given to those who have a uncontrollable urge to consume the online content of JellyBeamYT.
I was just sitting in my room when I started to feel an itch, one which could only be satisfied by my favourite YouTuber: JellyBeamYT. I hate my JCD, I can't go more than an hour without re-watching: 'BigK teamed with me and we fought' or 'CatRage escapes betrale.'
