Is it possible to make a wait that's forever long?

I've been making some debounce things with some scripts I've been using and I was wondering if It's possible to make a wait function go on for infinity so the script won't look messy. For an example:

db = true

script.Parent.MouseClick:connect(function()
    if db == true then
        db = false

        -- do stuff     

    end
    wait(9999999999999999) -- until can be pressed again
    db = true
end)

Obviously, I don't need a wait longer than that but my point is, is there any possible way to make a wait run forever without having to have it be "999999999999999999" It makes the script look messy.
