tweet stalking 

The act of following another twitter user, via twitter, in person. The process involves all stalking actions taken to be posted on twitter. The stalker also follows feedback from the twitter community in deciding their own next actions. Tweet Stalkers and those involved will @reply all tweets to the stalked's twitter name.

I am tweet stalking this cute girl while she is at work. Log on and help me out.

tweetstacking 

The practice of posting multiple tweets in a row on Twitter, usually to express something longer than 140 words.

Dan is tweetstacking again. Multiple tweets to say one thing? Seems self-indulgent.
