“Cat” and “copy” you may know. A copycat (imitador) is a person who mimics (imita) another mortal, or who copies material prepared or written by another person.

So the “copying” is not original and perhaps without permission.

Some examples:

• Mr. Zapotero is a copycat who mimics Mr. Bean (… es una copión que imita a …).

• He is a copycat.
