Nothing different than the way fraternity and sororities have been partying for decades. A reader sent us this photo of a Delta Upsilon "Poverty Party" at Tufts University in 1930 — right near the beginning of the Great Depression!
Apparently, making fun of those less fortunate than you has long been a favored frat party theme. We kinda like what he did with the bottoms of his pants, though.
