Cross the Streams 

When two or more males gather around a single toilet or urinal to see how many times each flow of urine overlaps until all participating males' bladders empty.

"Hey, Chad. Want to go in the bathroom and Cross the Streams? Bill and I counted to 59 last time. A new record!"

The Streamer 

A sad individual who legally changed his name to "The Streamer" in 2018 despite having less than 300 followers on twitch. He has made his own Wikipedia page and made his own entry for "The Streamer" on Urban Dictionary in a vain attempt to cultivate his own cult of personality, though the effort is entirely transparent.

"Have you heard of 'The Streamer'?"
"You mean that guy who couldn't find a job after Twitch failed to pay his rent?"

Crossing the streams bad 

When something is as bad as Egon's explanation of crossing the streams from Ghost Busters:
"Try to imagine all life as you know it stopping instantaneously and every molecule in your body exploding at the speed of light."
"Right. That's bad."

It's supposed to be really bad... No, I mean like, crossing the streams bad!

Cross the streams 

When a TV show/film is available on more than one streaming platform.

E.g.

Person A: “You haven’t seen the original Ghostbusters?!”

Person B: “Does it cross the streams?”

Person A: “Nah, it’s only on Prime.”
