The stereotype against George Washington students is that they are all rich, snobby city kids that are outspoken about all of these things. True or untrue, that's the stereotype. So in that light, I'm not really sure what to make of this video.
On the surface, it's simply a played-out parody of Wiz Khalifa's hit "Black and Yellow," except, of course, with the GW colors, "Buff and Blue." Setting aside the fact that the rhyming doesn't work properly because both "buff" and "blue" are one syllable, it's not the most original concept in the world, and therefore isn't particularly remarkable. (Hell, UVA did the same thing earlier today). But if you actually listen to the song, it includes the following lyrics.
"We own the IMF and the World Bank"
"60 G's out of my pocket, ain't go no debt"
"We college age, y'all just kids"
If the GW athletic department is unaware of the stereotypes they're representing, then I don't know what to say. If they are, and including these lines as some form of self-parody (which is more likely), then ... well-played, I guess.
