Why doesn't this debounce work properly?

local plr = game.Players.LocalPlayer
local char = plr.Character
local hum = char.Humanoid
local t = char.Torso



local deb = false

function onActivated()
	if deb then
		
		return
	
	end	
	
	print("Tool Activated!")
	
	deb = true

	local ball = Instance.new("Part")
		ball.FormFactor = "Custom"
		ball.Shape = "Ball"
		ball.BottomSurface = "Smooth"
		ball.TopSurface = "Smooth"
		ball.CanCollide = false
		ball.Size = Vector3.new(0.5,0.5,0.5)
		ball.BrickColor = BrickColor.new("Really black")



	local subject = Instance.new("Part")
		subject.Parent = t
		subject.FormFactor = "Custom"
		subject.CanCollide = false
		subject.Size = Vector3.new(0.1,0.1,0.1)
		subject.BrickColor = BrickColor.new("Really black")
		ball.Parent = subject

	local w = Instance.new("ManualWeld")
		w.Name = "Weldy"
		w.Parent = subject
		w.Part0 = t
		w.Part1 = subject

		w.C0 = CFrame.new(0,0,0)


	local w2 = Instance.new("ManualWeld")
		w2.Name = "Weldy"
		w2.Parent = ball
		w2.Part0 = subject
		w2.Part1 = ball

		w2.C0 = CFrame.new(0,0,2.5)




local angle = 0

	while true do
		w.C0 = CFrame.new(0,0,0) * CFrame.Angles(0, angle, 0)
		wait()
		angle = angle + 0.1
	end
	wait(5)
	deb = false
end


script.Parent.Activated:connect(onActivated)

Okay, I'll explain the problem im having.

You left click, a ball starts rotating around your torso. Everything fine. Debounce works fine 100% but:

If you left click, the ball appears rotating, the debounce countdowns to 0. and in that countdown iterval you start spamming left click. It jumps out the debounce and starts spamming and ignoring the debounce. Any help ?

I believe line 11 needs to be if deb==true thenbut it's very hard to tell... In the future you should properly indent your code as it will help you and other spot errors and make corrections.
