no mames

or ¡no mames! [noh-mah-mess]

What does no mames mean?

No mames is crude Spanish slang used to express disbelief (both positive and negative) or excitement. Used especially among Mexican Spanish speakers, the exclamation corresponds to “No way!”, “You’re kidding me!”, or “Stop messing with me!”. For instance, a statement of “I won the lottery” might be followed by “no mames.”

Where does no mames come from?

no mames

The Spanish verb mamar literally translates as “to suck,” so no mames can be said to mean “don’t suck (it).” There is some implication that the phrase is referring to fellatio, as mamazo is a term for that. There’s also some speculation that mames comes from the word mamadas, which loosely means “lies” or “BS.”

No mames is sometimes extended to no mames güey (no-mah-mess-goo-ee) and no mames wey (no-mah-mess-way), which both roughly mean “No way, dude!” Wey and güey are both Spanish slang words meaning “dude” or “guy,” though wey can also connote “idiot.”

No mames comes from the Latinx community and specifically from the Mexican and Mexican-American communities. There’s some debate about whether it was originally coined in Mexico, but many native users insist that it was. One of the earliest records of the phrase’s usage online is from a Spanish-language forum post on July 27, 1992. The term came to some prominence much later when actor Diego Luna taught it to comedian Conan O’Brien on his late-night talk show in 2015.

I question myself and then I realize… No seas baboso guey, ¡no mames! you come from a long line of luchistas. You don’t question why, you roll with the punches, le echas ganas, and as long as your heart is in the right place you hope and pray for the best. That’s all I can do.

His reasons for the Spanish lessons were legit since 41 million Latinos speak Spanish in the U.S. To put this into perspective, Spain has a population of 47.7 million people. By 2050, this country is set to be the largest Spanish-speaking country in the world with 138 million Spanish-speakers! ¡No mames!
