What things can you do in a tourney to stop people messing with your blinds without a hand?

I mean when it gets to the hijack seat and no one is in the pot, the people left to act start thinking, "hmm, I might take a shot at this".

I want them to look up and see that you're in the big blind and then think "actually I won't bother".

Ideas off the top of my head:-

-defend your blinds by calling down light a few times

-reraise a sizeable amount from the big blind a few times

-"Do not touch my blinds!" Then shove all in with a nonchalant back hand of your chips

Are any of these +ev if you're going to be at the same table with the same players for a decent amount of time?

Are there any other things you can do to stop people messing with your blinds that is not -ev overall?

Things you can say at the table even if it just works a tiny percentage of the time with a tiny percentage of players.

I dont think saying things at the table would stop them for coming after your blinds, the best thing to do is to 3b a couple of times but not a big raise just your average 3b I believe saying things like "do not touch my blinds" is like saying to villain that you are a bad beginner player cause noexperienced player wouldever type a thing like that in the chatbox
