TikTok Rat Brain

The deterioration or smoothing of one's brain due to excessive consumption of TikTok or other short-form media can lead to various symptoms. These include a shortened attention span, an inability to form complete thoughts, profound boredom when not mindlessly watching TikToks, and frequent references to "Skibidi Toilet".

"I need to stop watching TikTok, man. It's making it hard to focus."
"Yeah, man, I got that TikTok rat brain."

Rat Brain

When a dude stretches his scrotum tightly to one testicle and displays it. He could put it right next to a sleeping person's face, for instance. You could also just tightly wrap it to two testicles.

Dude, get your rat brain out of my face.
