What is Butt-talking?
1.
The act of beginning a conversational tangent on a topic you are familiar and knowledgable of, but then drifting off into areas of knowledge that the speaker "doesn't know is true for sure but preety sure it is".
When this happens, someone listening to said tangent may make the statement "now you're just butt-talkin." This act is usually followed by a small piece of Humble Pie served to the speaker and a belly laugh by everyone involved. Followed by another bong hit.
"Ya know, the human brain gets rid of weak and sick brain cells all the time"
"Really? Wow I didnt' know that."
"Yeah, and it's also known that alcohol preys on the weaker and sicker cells in your brain"
"Hrmm, interesting..."
"So, it's only common sense that when I start drinking I always feel smarter!"
"Well, now you're just butt-talkin!"
