4.
1) to be high on stimulant supplements(vitamins) or drugs.

2) to be hyperactive.
1) sugar, caffeine, monster drinks, sugar, earl gray tea, amphetamine, methamphetamine are examples of commonly used stimulants that can cause a person to be tweakin. They can become fast-moving, jittery and if on meth violently jumpy or shaky (trembling)

2) ADD/ADHD, natural high, sugar high, caffeine high can cause tweakin (hypetactivity) where you'll just be all over t he place moving fast.

when someone is hyperactive it doesnt mean they are under the influence of methamphetamine where meth high causes similar behaviour but is a different kind of hyper.
