Stim Head

A Stim Head is anyone that uses stimulants and uppers in their daily life. They choose an upper as their drug of choice, which can range from anything to coffee or cocaine, to adderall, nicotine, or speed in between. They like feeling wired and having unlimited energy (until they crash that is).
They generally like all sorts of stimulants, instead of an addiction to just one.

In any given week, you will most likely see them wired out or tweakin'.

Hey Emily, are you okay? You seem a little wired.

Yeah, I'm fine! Just popped an adderall and running off two coffees.

Jesus, You're such a stim head!
