verb/t͡ʃinˌɡaɾ a su ˈmadɾe/
to fuck oneself
“Ahora, si no le bajas de güevos a tu rompope, pinche pipope, te doy tu lana y te mando a chingar a tu madre —el poblano, a medio camino entre la vergüenza y la furia, se acurrucó contra la ventanilla—. ¡Y no soy chofer! —remató.” — “Now, if you don’t calm down, fucking pipope, I’m paying you and then you can go fuck yourself.” The Pueblan, halfway between being ashamed and furious, huddled against the window. “And I’m not a chauffeur!”, he added.
Literally, “to fuck one's mother”.
