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.

Pendejo is a single pubic hair. In Mexico´s slang it is used as an insult like idiot or fool, but in Peru´s slang it used to describe a smart guy with few or no scruples.

Spanish slang for "asshole"
