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."

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

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?

Catbomb 

Verb; The act of cheerfully spamming a friends facebook wall by Liking as many posts as human possibly, and adding an absurd number of cat/kitten videos. Usually performed at night while the victim is asleep. So upon next arrival to "Facebook." They are shocked to see around 150+ notifications and get extremely uneasy. Then to settle this uneasiness dozens of kitten videos! Wooo!

1. Like every post done by the victim, on the victims wall for 3+ years preferably. Remember it is all relative to how active the victim is with Facebook, and as well get your friends involved in this let them know to like everything that. The goal is as many notifications as humanly possible.
2. Post as many cat/kitten videos as human possibly. Be creative with the postings. Add your own personal flare to it. Create your own reaction photo/video.

3. Once the Kitten mayhem has been unleashed. Start to Like every video you posted. Again, Let your friends know, heck let anyone know who knows the victim to like every cat video that has been posted.

"Megan help me Facebook Catbomb Heather we need to get her back and she has been sassing me quite a bit, as of late so let's get her back in a cute yet witty way. Let us Catbomb her ass."

"Yo, Alex I just cat bombed my girlfriends older sister"
"oooohh CATBOMB"
