wollof

In social media, especially Twitter, it is the act of unsubscribing to celebrities, companies, people or organizations in order to avoid reading the thoughts or ideas of said entity.

Sometimes you will see on TV or hear in commercials where a company will ask consumers to follow them on Twitter. If you do decide to "follow" them but then stop following them, this is described as a wollof. As you can tell, this is a reversal of "follow"

John : "I used to follow Sarah Palin just to see how inane she is but I can't take any more, I think I will wollof her"

Jack : "I have a simple rule, I will wollof anyone that does not follow me back after I say hello. A twitter conversation is a two way engagement"
