How do I exclude infrequent usernames from mysql query?

Question

I have this code

SELECT usernames FROM table1

I want to select every username from table1 however I want to exclude usernames that appear less then 5 times in table2 .

So I want this: Select all usernames from table1, but exclude the ones that appear in less then 5 rows in table2.

How can I do that?
