This is not a rap star. EasterB is the Easter Bunny who has been trying to muscle in on Christmas for many years. At first he invaded a neighbouring commercial opportunity, which forced Santa to arm his sleigh and lead a coalition to evict the Easter Bunny and his army.
Since that time, the Easter Bunny has been skulking around somewhere in April (changing the date every year to confuse his enemies), licking his wounds and waiting for a chance to take down his arch-nemesis, Santa.
