Another word for penis. This word's origin is incredibly mysterious, but nonetheless, it is what it is. It is said as if it were a Spanish word, although again, it is not. Well, at least not to my knowledge. Thus, it is pronounced with a soft r, NOT a hard r. Almost like a "d" sound. Anyway, yeah. pinera.
"Hey, why's your girlfriend getting so fat?"
"Dude, why do you have to be such a big pinera?"
