A sumo suit is just a huge padded yellow thing you wear to appear really fat, like a sumo wrestler. It comes with a shiny black wig, complete with sumo wrestler top-knot. So you get a couple of these suits and pretend to sumo wrestle, while your fraternity buddies stand around cheering you on.

For the grievance lobbies this was a twofer. One, there's the cultural appropriation of white kids dressed up as Japanese. Then two, there's the whole fat-shaming thing. The quantity of grievance here was enough to bend light.

Quote from student Phil Jones on his Facebook page, quote:

I was shocked. February 19th was Remembrance Day for Japanese internment during WWII, and some of my Japanese friends were heavily traumatized by seeing their culture mocked in such a clearly racist fashion. Not to mention, as a heavy-American, I don't appreciate the blatant Fat-Shaming involved with caricaturing one of the few sports traditionally enjoyed by Heavy individuals.

That's the first time I've seen the phrase "heavy-American" in print, hyphenated. I doubt it'll be the last. What next? A Department of Heavy Studies? An NAAHP? Heavy Lives Matter? It can only be a matter of time.
