Looking to make a kick on death with a delay?

Answers by greatneil80 and Nowaha are what you are looking for. Use delay after died function, here is how it should look like: (Normal script inside ServerScriptService)

local Delay = 2
local Reason = ""

game:GetService("Players").PlayerAdded:Connect(function(Player)
    Player.CharacterAdded:Connect(function(Character)
        Character:WaitForChild("Humanoid").Died:Connect(function()
            wait(Delay)
            Player:Kick(Reason)
        end)
    end)
end)

To make a delay anywhere in your code, you can use the wait() function.

wait(2), in example, will wait for 2 seconds before it continues with the code below it.

-- Code before waiting
wait(2)
-- After 2 seconds, everything below here will happen.
