rofl monster 

The rofl monster a distant relative to the big blue bear from the "hug in a mug" advertisements, however he is neither friendly nor does he gives hugs. he is a crazy psychotic monster that dwells in rehab for his addiction to snorting santa claus's man juice. If one describes the physical appearance of the rofl monster, then he will hunt that person down and visciously bum them until they have no anus left. The rofl monster's victims have often been admitted to mental hospitals after their dreadful experience

Gregg: Oh cheesus, Steven was visited by the rofl monster after describing him to Lucy yesturday
Dave: Nooooooooooo! hows his anus?
