1) A constellation with
5 stars in it in the
Northern Hemisphere
2) The name of the fan club of
DBSK, a popular Korean boy band. It's ridiculously notorious for acting psychotically negative towards anti-fans. Those girls are literally an army and will do whatever it takes to make sure their boys are not bashed or any negative shit like that.
There's this guy named 60row who said on his myspace that
DBSK made
shitty music, so cassiopeia
tracked him down and beat the shit out of him
