How does Walter insult george in the book A Raisin in the Sun?
Mainly what the background on that part/scene was to show that the author made Walter drunk for a reason on that scene to make him speak his mind through his drunkenness so when George was speaking to Walter that's what he was really feeling but it was set up in an oblivious way so she put it as the "drunk" Walter saying that.
But he insults him by saying "And you-ain't you bitter man?...Bitter? Man,I'm a volcano.Which is mainly starting how rich his father is and how Walter would rather be in George position than his own.
P.S. were reading this book too.
Hope this helps!Good Luck.
