twituperation 

Twitter attack with harsh, often insulting language.

@Beaker gave @ruv a severe twituperation for being a clown over the open cloud manifesto.

twitteration 

the feeling you get when a friend you've been following on Twitter finally follows you back.

I felt an intense twitteration when I saw @PamelaDAnderson finally show up on my Twitter followers list.
