- I’ll holla back atchu, dog!
Atchu
noun; blending
At you, to you Since most of the sentence is said in slang, atchu fits perfectly in the context. It combines words and drops letters and changes endings the same way holler is changed to holla in the same sentence.
Etymology : Blending of 'at' + 'you'
