BJ5 is another term for Rift Raid of the 5th level in the Korean Role Playing Game, Summoners War. It is name this due to the shitty programming by the games developers, Com2uS, that most "loot" obtained from the drop table is just as shitty and undesirable. Leaving you with the feeling of being fucked over and with a case "blueballs" like a bad blowjob.
