Brain hole

The place in your brain where you put new information. It's also where you pull ideas out of.

"Candice named her twins Bucket and Bracket, what in the fuck is wrong with her brain hole?"

"I literally shit in the refrigerator last night because the liquor messed up my brain hole. And the shit is still in there."

brain burp

When an irrelevant comment slips through the mouth before the brain has a chance to filter it.

Example:
"So if the government wants to fix this situation there going to have to-"

"Bananas are great"

"What does that have to do with anything?"

"Sorry, brain burp."
