Snapcamping 

When someone sits in the a snapchat chat while you're typing out a message so their bitmoji appears.
Can be extremely annoying as you are pressured into typing quickly instead of thinking out a message.

Person 1: She was constantly in the chat last night, I couldn't leave without ignoring a message
Person 2: She was snapcamping you
