South american insult. Concha means vagina in Argentina, Puerto Rico, Chile and sometimes in other Latin countries. Concha is also a sea shell but the shells are usually refered to as conchitas (little sea shells) to avoid saying cunt. While, concha-tu-madre is an insult, latin women do not always find the use of the word concha as a body part to be as offensive as english speaking women find cunt to be.

La concha de tu madre! = Your mothers cunt!

Concha es tu madre! = Your mother is a cunt!

Yes, technically it means the Mexican sweet bread or “pan dulce” and it’s also a slang to mean a woman’s vagina, but this NEW meaning is defined as someone that’s soft like a concha and a “pussy” in terms of when a person(typically a guy) is a afraid to do something that requires a risk or precaution(s).

Concha(noun): to be weak or afraid to do something. A coward.
Tequan: Bro, Jennifer has been checking you out every morning before shift. You should get at her.

Payton: Ahahaa nooo, Bro Bro. I’m good. I doubt she’s checking me out. She’s always smiling. Because she’s just nice.

Alejandro: Payton, stop being a freaking “CONCHA”. It’s now or never. And what’s the worst thing that could happen? File a report a that you harassed her? Hahaha

Payton: Concha? Isn’t that the Mexican bread? How am I a concha?

Alejandro: It means you’re soft bro. You’re scared and cowardice to do something. It’s just a joke.
