Why is part of the script running for the number of times that I right click?

I'm trying to make a script that will grab an npc in which you can throw them afterwards.

if input.UserInputType == Enum.UserInputType.MouseButton2 and clicked then
        local welddb
        clicked = false
        if firstrc then
            firstrc = false
            GrabHitHandling = humanoid.Touched:Connect(function(hit, limb)
                if not isGrabbing then
                    grabAnimate:Play()
                    wait(.55)
                    if limb.Name == "RightHand" or limb.Name == "RightUpperArm" or limb.Name == "RightLowerArm" then
                        isGrabbing = true
                        target = hit.Parent:FindFirstChild("Humanoid")
                        if target then
                            EntInv:InvokeServer(player, target)
                            GrabbingVar:FireServer(isGrabbing)
                            local d = target.Parent:GetDescendants()
                            grabbedAnimate = target:LoadAnimation(grabbed)
                            grabbedAnimate.Looped = false
                            for i = 1, #d do
                                local desc = d[i]
                                if desc.Name == "Head" then
                                    if not character.RightHand:FindFirstChild("Weld") and not welddb then

                end
            end
        end
    end

For some reason, past the

local thrBody = throwBody:Connect(function() 

line, everything is printing for the number of times I have grabbed and thrown in that run. Any ideas?
