chat bomb 

When a few/several people send messages to each other in a group chat that there are so many of them (50+ messages is considered a chat bomb.)

Oh god, it's time to scroll up to see what's going on. Why'd they drop that chat bomb?

Bomb the chat 

When a person or friend spams a direct message, facebook message or any type of group chat. This is often to such an extent you think your phone will explode or lags the chat badly to where it is a pain to type.

'Dude why did you bomb the chat yesterday'
'Lets troll our friends and bomb the chat'

chat-bombing 

When you and one or more friend(s) are sitting next to each other on various computers and typing the exact same message to one person on facebook chat, thus confusing the person to tears and/or laughter.

Let's go chat-bombing on Facebook!

chatbomb 

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."
