"Eu marco o meu território."

Translation: I mark my territory.

[Danmoller]

Like a dog does with trees, a man shows he is the one who gives the orders there.

[ProBugCatcher]

Or a woman.

[Danmoller]

A woman doesn't "mark" her territory.
She silently controls the minds of those who "mark".

[cloudhorizon]

You haven't met enough women then. :P They're just as territorial, if not more. (Probably more)

[motherwind]

What exactly does this expression mean, as written, in Brazil? Surely not its literal translation in English.

[MariaSilfverberg]

Is the meaning of the use of "o" here that the territory is definied by something, in this case by "my". So maybe it could be a rule of when using the articles?
