Known as the bigass monster that eats guys for the hell of it from the English epic, Beowulf. Something referred to as Grendel has to be big, dangerous, and dominant. It can be a hungry fat guy, a relative of Jabba the Hutt, Britney Spears-Pregnant Style, or even the moustache on Wilford Brimley. Whatever it is, it's disturbing to the general public.
1.) Hey little Billy, you better stop hangin' around with that Grendel, you might suddenly be absorbed.
2.) Dude, that guys got Grendel on his face!
3.) It's Grendel: Live on Broadway, starring the pregnant Britney Spears as that...thing.

 Get the Grendelmug.
Get the Grendelmug. An antagonist from the epic poem Beowulf, recently rendered in movie-form as a somehow sympathetic foil character resembling, as quoted on IMDB by some guy; "A decomposing, half-reptilian Joseph Merrick on crack". He has awful neighbours, a bad case of swimmer's ear, speaks in bastardized Old English, and suffers a fatal dismembering by some naked drunken man nobody was paying attention to. Easily the only thought-provoking character in that entire film, if you weren't busy being hypnotized by Angelina's nippleless mind destroyers.

Get the Grendelmug. Based on the character from the Anglo-Saxon tale Beowulf. Refers to someone who stays locked up in their room, with the curtains closed, and only wants peace and quiet. If their wishes are not met they will huff and puff and possibly even massacre a large group of people.
