You think that you could stand toe to toe with a bull, and not flinch?
Below your pants, you'll be wearing knee-high white socks. Or, at least you'll look like you're ready.It's okay if you want to use the figure of speech, and maybe use the saying figuratively in other scenarios, but if you end up face to face with a bull, just, please, don't grab it by the horns. You'll also be wearing a foam Montera-style hat and a bright red cape, the most important pieces of any matador costume.
