stimulant 

The word "stimulant" can refer to any type of drug that increases activity in the central nervous system or sympathetic nervous system, ranging from caffine to methamphetamine.

The most common recreational stimulants are commonly called "uppers" and include ADHD medications (adderall, ritalin, etc), amphetamines, cocaine, and ecstacy.

The more addictive stimulants generally give the user a sense of euphoria that might include alertness, possible twitching and an overall sense of well-being.

Nicotine, the addictive subtance in tobacco, is a well known stimulant but can also be sedating in higher doses.

E: Yo, i got a lot of fuckin work to do tonight, you know anyone that can sell me an upper or any stimulants in general?

Simultanatelephobia 

The fear of trying to call someone at the exact moment they are trying to call you, and thus being irrationally afraid to pick up the phone for fear that the party trying to reach you would receive a busy signal. This mental illness was very common before the advent of "call waiting".

The nervous bitch wouldn't let anyone use the phone because of her simultanatelephobia.

simultaneous equation 

equations involving two or more unknowns that are to have the same values in each equation.

If an equation has two unknowns, such as 2y + x = 20, it cannot have unique solutions. Two unknowns require two equations which are solved at the same time (simultaneously) − but even then two equations involving two unknowns do not always give unique solutions.
This gives us a 'simultaneous equation'
