This is not an ADHD sympton itself but it’s often a mechanism developed by ADHD people as a way of distracting themselves and getting a dopamine hit. Lack of dopamine is a symptom and everyone fights with it a little differently.

Are you kidding me, this is also an adhd thing??

Nah, the most ADHD person I know doesn’t suffer from this and I know plenty of non ADHD people who do. I think it’s just some form of addiction
