This is a common word to explain when a male massages the scalp of a female that he is attracted to or friends with. This method is usually only done with one hand and executed in a social gathering.

Get the Brain Slurp mug.
When you are so out of it that your brain feels like mush. As if you could stick a straw into your ear and slurp your brain out.
"I can't stop giggling right now. Major case of slurp brain."

"I'm so out of it."
"Slurp brain?"
"Yes, it's all mush up there right now"
