Get...out...of...everyplace!

[Marquetta]

A derivative of the old worn-out phrase [get outta here]!
Said by someone to communicate either :

disbelief, or

a desire to, swiftly, end the conversation or move onto to a new topic

This new version re-kindles the emphasis and weight that its [predecessor] had lost through overuse.
Often said with a pause to indicate that the speaker has upgraded the statement mid-sentence.
A Brit first overheard it being said by a camp person in L.A and then propagated it to [Essex], UK. Therefore, it MUST be said with a fake, camp, US accent every time.
