There are a couple different kinds ways to have a big mouth. Basically someone that can't keep anything to themselves.
One is the type of person that cannot keep anything secret.
Another is the
sort that always
shoots off their mouth to everyone for any reason. Such people tend to get themselves into trouble because they're always
pissing people off. The type of person that in an argument will keep
arguing and arguing far beyond the point where they've made their point and should stop.
A)
Ack, don't tell him a secret. With his big mouth everyone in the world will know within five minutes!
B) This guy I know is always getting into fights because of his big mouth. He'll
lip off to anyone for any reason and tends to take arguments a lot
farther then any normal person would take them.
