If all you want to say is that the expression is used too much, say "overused". If you also want to insult the imagination or creativity of the person who uses it, call it a "cliché".

Umm im English and i really dont know myself tbh 😂, i was just say its overused or something. Also im learning Russian so we can exchange languages if you want?

A cliché is usually something oversaid such as: you only live once! I would say I'm happy is just a boring adjective. I tell my students to 'say it better' or to think of a more expressive adjective. I don't think havkneyed or clichéd fits your example. Possibly don't overcomplicate things and just refer to 'interesting vocabulary '. Hope my thoughts are useful, Zowee

The one that popped into my mind was "a hackneyed phrase," but I agree with Jonathan that "overused" is more straightforward. We don't say "a cliched phrase," we say "a cliché" (or "a cliche." I think it is better to include the accent mark, but it can be left out.) The word has an interesting origin in 1900s printing technology. It refers to a process for producing dozens of identical copies of a page of type, and is an imitation of the sound of the process.
