A person who parasitically latches on to a celebrity tweeter, incessantly retweeting and tagging them to draw popularity in a manner similar to that of a leech drawing blood.
Person A: MattandDavid tagged me in a tweet, and now I have 1263 followers!

Person B: How comes?

Person A: I re-tweeted and tagged them non-stop for 14 hours, so I think it's a payback thing.

Person B: You utter Tweet Leech.
