MSB
In the Cleveland area, MSB is the abbreviation for the local band the Michael Stanley Band. They had 2 national hits in the Eighties, "He Can't Love You (Like I Love You)" - a Top 20 hit in 1981, and "This Town is My Town" from 1983. A special version of the latter song was played on radio stations in the Columbus, Ohio area that has a shouted chorus "COLUMBUS!" added to the mix. MSB is also the title of the group's 1982 album, and to some critics it also means "Mighty Shitty Band".
In the metropolitan Cleveland area, many Michael Stanley Band fans wore jackets that said MSB on the back. There are some items from that band at the Hard Rock Cafe located in a mall in downtown Cleveland.

NOTE: The Mario Social Board is actually the Mario Games Social Board... However, MGSB is taken by the Metal Gear Social Board... >_<
