textcrastinate 

To delay/wait texting back someone who has sent you a text in order not to appear overly excited about the fact that they texted you. This is especially true when it is someone you are interested in.

I'm so excited....John just texted me! I am going to textcrastinate as long as possible before I reply.

twitcrastinating

Rather than doing anything useful in the world, you spend hours on end reading comments, following RTs, and picking up new followers by pursuing other twitterer's followers on Twitter.

Yeah I'm facing a huge writing deadline, but I'm caught up twitcrastinating instead.
