SS501 (pronounced as Double-S 501 or Deo Beul E Seu Oh Gong Il) is a popular South Korean boyband under management of Daesung Entertainment, also known as DSP Entertainment. The name of the band is a combination of the alphabet and numbers that have special meanings in them. The first “S” stands for “Super”. The second “S” is an abbreviation for whatever they want to be that starts with an S, Star/Singer etc. The number 5,0 and 1 means `five members united as one forever.’ Their official fan club is known as "Triple S". There are only three official Triple S currently, but more are surfacing from other countries and waiting for DSP to recognize them.
