I gather it was some kind of music that people find drippy, and that by extension it’s been applied to sensitive young men. Is that the case? Apparently people consider the term  a sure put-away insult. From a thread on Sandman at TCJ’s message board, JL Roberson calls Gaiman’s Sandman “Emorpheus” and adds, “sorry, but it’s true, and Dave Sim’s parody of him sums up all that you need to know about him.” As I recall, the Sim parody character was named Swoon and wouldn’t have been much good at football.
