Can someone help me with the translation of this phrase?

「人の縄張りででけぇツラすんじゃねぇよ！」

I understand the basic meaning, and that it's very coarse language. I just can't think of a phrase in English that carries the same meaning.
Also, just for clarity, does 「人の縄張りで」 in this context mean 'within someone's territory' or 'at the border of someone's territory'?
