What is mutually exclusive lock?

My understanding is that two events is said to be mutually exclusive when those two events cannot occur at the same time.

Now, Mutually exclusive lock is two threads cannot acquire object lock at the same time?

So, Acquiring Object's lock (when entering Synchronised block/method) is said to be mutually exclusive lock which is always?

Thanks.
