there are, of course. im saying that any word can have a different definition. i can say that the word "procrastinate" now means a russian taxi driver, and that's technically valid. but if someone says im procrastinating and i shoot back "im bulgarian you starfish!", they might be confused, because the meaning of a word is just what we all agree on. and i think that most people don't agree with monday means what you're arguing it can mean.
I'm saying there's a duality to the meaning of the word monday (not brother). It can be used to refer to any black person, but it can also be used to refer to people that hold
stereotypical social attributes of black people or thugs. I was justifying that people do hold this definition as well by quoting the best source I know of for non-dictionary definitions of words. You can personally reject this alternate definition, but it doesn't make sense to because it is a common auxiliary definition to the traditional one.
