As noun, my foes find me traumatic
(Balls! they say - quite cinematic).
As verb, my use ain't systematic;
but phrasal, my limbs go erratic.
Very specific knowlege, thus probably unhelpful, tip (but I couldn't resist):
Why did they make ages 5 worse than 4. I can't be taking my boots on and off!
Are you a
Flail?
Because
as a noun, you are a primitive weapon, such as a morning star
as a verb, you are waving your arms around erratically
and in a phrase "flailing your arms" your limbs move erratically
However,
I can't tie it in with the title (unless an ancient William is associated with the weapon, which I couldn't find) or the tip.
