Jack-in-the-box-pop-up-artist - A f***ing nightmare that shows up outta nowhere and vanishes

A f***ing nightmare that shows up outta nowhere and vanishes before you can even f***ing blink.

My mom showed up at my apartment like a f***ing nightmare and left before I could even f***ing yell.

That guy from the gym popped up at my work and vanished before I could even f***ing say hi.

My friend showed up at my concert and left before the f***ing encore started.
