Tweetseeking 

Where you enter a purposely vague tweet in order to gain sympathy and attention such as 'I feel really low today' 'Don't men ever get what we mean' etc. The result being that a large portion of your contacts instantly wants to unfollow you. Note; this is the Twitter version of Vaguebooking

Shirley: 'I hate feeling like this'

Everyone else: 'oh no Shirley is Tweetseeking again!'
