desmedirse

A reflexive-only verb meaning to overstep the mark or go too far — no te desmidas con las bromas (don't take the jokes too far). From medida (measure), the same root as medirse (to measure oneself, to be measured/restrained).

• Se desmidió con los comentarios en la fiesta. — He went too far with his comments at the party.
• No te desmidas al pedir el aumento. — Don't overreach when you ask for the raise.
• El árbitro se desmidió con esa sanción. — The referee went overboard with that penalty.

Using it without se — desmedirse is reflexive-only; there's no plain transitive desmedir used in modern Spanish.
