When you send someone a text, but you accidentally send it to someone other than the intended receiver. On purpose. Coined by Larry David.
In the accidental text on purpose, you say something like "Hey Larry, you were an asshole the other night. There's nothing wrong with her water, it's perfectly okay."
When you're using Facebook messenger and you accidentally hit the thumb on the right side of the screen. It sends it right away, so there's no going back. It's an oversized blue thumb that gets inserted into your thread of texts. Often happens when you're having conversations that would be totally inappropriate to give a thumbs up.
Two people messaging on FB:
Johnny: "I just got back from the vet. My dogs eye was bleeding from the inside."
Daphs: "(thumbs up)"
Daphs: "Shit, that was an accidental thumb. I'm sorry to hear about your dog."

Unlike a Troll, who deliberately intends to cause maximum disruption and argument, An Accidental Troll, is a normal user who speaks their mind a little TOO much through forums, and accidentally gives off the impression that they are a Troll, when clearly, they have little/no time and have a lot to say about the topics that are being posted.
BobMoney63: Hey, that guy is Trolling, ban his ass!
Admin: Nah, I've read through his posts, he's an Accidental Troll. He just has a lot of time on his hands, and has a lot to say about the topics that are being posted.
