instinct boner 

An erection that occurs when a man becomes tired, but is fighting hard to stay awake. Instinct boners often occur during boring lectures or when driving late at night and will not go away as long as the urge to sleep persists.

Origin: In order to protect their food supplies and sleeping families from scavengers, early humans evolved the process of instinct boners by frequently masturbating to stay alert while on cave watching duty.

I could not stay awake in class today. I had a huge instinct boner and I spent most of the lecture trying to sneakily tuck it under my belt.

Ultra Instinct 

Form that allows you to subconsciously dodge even the miniscule of things. Essentially, you're fully aware of your surroundings, like you have an eye with circumscopic (360) vision, as well as extremely advanced perception. It's timed though, so eventually you'll revert to your regular form and lose all the benefits.

Ultra Instinct: Imagine you running away from your mom when she's trying to whoop your ass for no good reason. That is, until you lose UI and she begins to whip you like you've never been whipped before
