Get the hotness monstermug. This kind of beast rules the underworld of livid, vivid sexual theatrics. It is one who watches porn by day, up to 60 pornos that have been saved in the deps of his personal computer. By night this death walker watches their roomate talk to their girlfriend for hours planning on ways to shut them up. It is a person who has extremely intense sexual frustrations that are heightened by his lifestyle and environment in which he lives.
I was walking down the hallway when out of the corner of my ears I heard the wild yelp of a chained sieh monster. I opened up the doo and there he was planted in front of his porn ladden computer like a deer in headlights.

Get the Sieh Monstermug. Little green and purple creatures, that run around and do crazy stuff. All they do is boom and drop acid all day, and the only way they can die is if they OD. They are Grown mostly in South America, and they dance all day long until they are full grown(they get about a foot tall). All they say is "KRICK" and nothing else unless you teach them.

Get the monster rainmug. An energy drink that people drink to seem cool and lower class. Tastes pretty good but has been known to kill people because they take too much. Looks 'cool' for a teen to drink it but immature and retarded for an adult.
