The new over-used but not yet killed use of the original meaning of "but". Used to start
short statements with the intention of emphasizing ones
point on a particular topic.
Usually said very quickly so it sounds
like a mumble, and is recipricated by another sentence beginning with "but", this goes on back and forth for quite a while
un till someone decides to say "i know".
"But i am"
"But he is"
"But its not"
"But i cant"
"But they do"
"But i will"
"But we must"
"But i know"
"But you did"
etc....
