The usually one-sided banter of Dave Matthews that takes place in between songs (usually) at a Dave Matthews Band or Dave and Tim show. It can be anything, such as random phrases and facts, mock dialogue, or an interesting anecdote.
Examples of Davespeak are:
“this is a song about little pink drinks that look like condoms...”
“Remember that there are hundreds of thousands of things you can eat that are not cheese.”
“This is a song about somebody I was fucking...no, this is a song about somebody thatI really liked a lot....maybe, I don’t know...and I happened to be at the same time that I really enjoyed this person..fucking her at the same time."
"a goat's penis is much like a pencil but shinier and pink. but in that pencil is the power to create life."
