A word often used to describe dangerous
dog breeds such as Bullterriers (Pitbull, Stafford) and Mastiffs (Rottweiler, Dogo Argentino, Boerboel) because they tend to have large jaws, sharp
teeth and muscular bodies, which goes with the ability to severely injure and
kill other humans and animals.
"My crappy neighbour recently bought an American Pitbull Terrier, the jaw was so
huge that it reminded me of some kind of land shark. I heard they
kill more
people than all other breeds combined!"
