get - it? Said fast usually after you tell a joke and to wait for a response to the person you told it to, particularly if it's a tricky or subtle or to avoid causing offence etc.

Basically emphasize the point you made a joke and/or check they understood.

Of AnCom origin, the term refers to graffiti where in "Liberals get the bullet too". This was shortened to "They will get it too" then simply "Geddit". It is an implied threat against anyone who the individual stating the term thinks of being an enemy of "The People". In short, "When the revolution comes, X will be killed."
All white people are racist. All white middle class, white working class, white men, white women, white gays, white children, they can all Geddit.
