When a large portion of a Video Game's fanbase consists of teenagers who make the game their entire personality despite only watching a few cutscenes and seeing a lot of memes.
I miss when DMC5 wasn't just a game known for memes, the game's been suffering through Jetstream Syndrome a lot recently.

To ejaculate into a partners face through the use of a high power fan, rather than traditional means.

Speculation of the origins of the German Jetstream date back to WWII, where it was thought that Hitler would use the German Jetstream on Eva Braun. The use of this technique allowed him to taunt allied attacks with threats of Advanced German Jetstreams. It was believed to have been a plausible origin, as he was able to conquer europe by jizzing into a fan.
You're fucking a girl, and right before you cum you bring out a fan. You jizz into the path of the fan, thus hitting the females face through indirect means by way of the breeze. Afterwards you ask the female "how was that German Jetstream?"
