It means you are attempting to perform an operation that would be blocked, but the operation does not permit blocking. Oracle issues TM locks to ensure that the structure of a table is not altered while you are modifying its contents. For Example: if you have updated, inserted, or deleted a table, you will acquire a TM lock on that table. This will prevent you or other users from executing DROP or ALTER commands on that table. Therefore if you attempt to perform DDL on the table while you have a TM lock on it, you will receive the ORA-00054 error message. To release TM lock do a commit or rollback then try dropping the table again.
