pendejo is a spanish slang word for idiot,stupid or dumass.
El es un pendejo. He is a dumass.
On the west side of San Antonio, Texas, I discovered that pendejo means more than just "stupid" which is what I had been told. The conotation on the west side had more to do with being called "a fucking idiot." Naturally, this was not taken too well and required some fancy explaining to get out of. Tex-Mex slang is tricky stuff.
Hey, stop being such a pendejo.
Spanish slang for "asshole"
Tu eres un pendejo Pedro! You are an asshole Pedro!
