A goblin-like midget standing 3 foot 12, with the face of the hobo and the ears of an elf. Noted for grunting, farting and saying with a sneer "Me name is Bumpaclaus, and you been bad dis year."
Comes to the houses of sinners each Christmas to empty the contents of his little anus. He smokes all your herb, drinks all you rum and wipes your walls with his little bum.
Usually disappears with a flash and a spark, leaving behind a tiny skidmark when threatened.
First documented by Uzimon, international reggae superstar.
You've had a visit from dear Bumpaclaus, my friend.
