A statement or gesture that creates instant chaos in a live chat.

Ex. 1: When accepting a game award for Overwatch live, you state "keep them out for Harambe".
*chaos ensues*

Ex. 2: Bob Ross, being streamed on Twitch, pulls off the border surrounding his painting and collectively blows everyone's minds.
*chaos ensues*
One might say, "Damn, Jeff just dropped a Harambe chatbomb. That fucking madman."
Or maybe, "No one drops chatbombs like Bob Ross. He drops chat-carpetbombs."

Get the chatbomb mug.
When someone adds a lot of people to a chatroom with the intention of ruining it.
"Dude, John just chatbombed again!"
"What?"
"He added 400 people to our chat...Now they're just putting porn everywhere!"

The same as a photobomb, except you say hi and immediately log off of whatever chat you're in.
