When someone doesn't brush their teeth, gives you head, and you don't shower for a while, allowing tooth butter bacteria to expand upon the head of your peepee, giving you Balanitis.

brain fever

(noun) A belief that "crazies are great in bed." Coined as a parallel to "yellow fever" for fetishizing Asian women, "jungle fever" for fetishizing Black women, etc.

It's not always easy to distinguish someone with brain fever from a partner who's merely willing to support you through your mental illness.

Brain Muffin

A brain muffin is an original concept coming from you that is a detailed epiphany. It's akin to baking a muffin in the oven. It takes time and the right ingredients, and eventually a tasty treat.

These treats are thought-provoking ideas that are fresh-baked regularly. Think of them as idea stubs that could become an idea cake. (Generally, you'll develop brain muffins into something bigger, but you don't have to.)

I had a brain muffin today about how i can use peanut butter to get my dog to take his pill.
