Yep. A guy named Taco. I looked him up and it actually showed up in the suggested searches on Google. Turns out he was drafted by the Cowboys in the first round, 28th pick over all.
His real name is Vidauntae. According to Wikipedia, the "Taco" nickname came from his mom and grandma. No explanation is given. Kind of wondering if it wasn't just easier for a sibling to remember. That is why one of the kids at church is called Sissy. Her older brother (who was 4 when she was born) couldn't pronounce her name (it is some Native American name, but I can't remember how to spell it.)
Here is his Wikipedia entry for more info on his career.
