full-brain

Using your brain fully for task, rather than using letting an AI do it for you, or even assist you with it.

In the context of code, it is a strict antonym to vibe-coding. Instead of letting an LLM generate your entire code base, you full-brain the code and write it entirely yourself.

Did you see Cory's homework? Completely AI generated and he still got a 100! I full-brained mine and I got a 67, WTF

Hey, sorry I wasn't able to implement that feature today. I ran out of my AI usage limit, so I had to full-brain the rest of the code.

Fullbring 

Literal translation: Manifestation art (obviously fullbring is better, right?). It is an art of maximising the capacity of an object you hold dear by pulling out its 'soul' and resonating it with yours. It could be anything as every object has a 'soul'. Hence the object with which you're most functional is called your FullBring

Girl: (exhausted) That was great, Melissa! How did you do that?
Melissa: I thought I told you, this strap-on is my fullbring.
