How to use debounce correctly?

I'm pretty sure my problem is debounce not being used correctly. The despawn part doesn't work and despawns the part for like 1 second. If someone could fix this that'd be great thanks.

debounce = false
script.Parent.Text = "Spawn Pet"
script.Parent.MouseButton1Down:connect(function()
    if debounce == true then return end
        debounce = true
 local plr = script.Parent.Parent.Parent.Parent.Character
 owner = script.Parent.Parent.Parent.Parent.Name
 part = Instance.new("Part", Workspace)
 part.Anchored = true
 while wait(0.1) do
  part.CFrame = CFrame.new(plr.Torso.Position + Vector3.new(5,-2.4,5))
    script.Parent.Text = "Despawn Pet"
    part.Name = (owner.."'s Pet")
    script.Parent.MouseButton1Down:connect(function()
        part:Destroy()
        debounce = false
        end)
 end
end)
