Either this thread of that G&D post on RTB is a joke.
"monday" can also mean white people too, therefore making it not tribal. It's only tribal if they say something that directly offends a race, like:
"black people are harder to see at night than white people. thats why I hate when they jump out of the palm tree leaves and attack me.
only black people. they're idiots" -No offense, it was an example
