Después de escuchar sus quejas por horas, finalmente le dije que se fuera a tomar por el culo.

[morbrorper]

English Translation

After listening to his complaints for hours, I finally told him to shove it.

If you pardon my French, I think “tomar por culo” (without the article) is more common.

Give @morbrorper the spanish citizenship NOW!

I agree with you without the article is more common, but both are correct and used.

[morbrorper]

You are much too kind, sir!
