1.) A cube in the game Portal you are given to help you with tasks.
2.) Your best friend.
1.)This weighted companion cube will accompany you through the test chamber. Please take care of it.
2.) While it has been a faithful companion, your companion cube cannot accompany you through the rest of the test. If it could talk - and the Enrichment Center takes this opportunity to remind you that it cannot - it would tell you to go on without it because it would rather die in a fire than become a burden to you.

It'one of a kind. Better than friends with benefits, while not being in a commited relationship.

- Together wtf?
- I though he is your bf.

- Ah no. He is my Pleasure Leisure Companion.

The most beloved "character" in the Valve game Portal, it is considered a character in most tenses of the word due to its helpfulness and aura of friendliness, though it does not talk, and thus cannot threaten to stab you.

The Companion Cube is only used in one level of the game, but it leaves a lasting memory and somewhat of a motive for the main character to "kill" GLaDOS, the antagonist of the game.

The main character, however, does not seem to have as much of a link or heart felt connection as does most other test subjects of the Apeture Science Computer-Aided Enrichment Center. This is shown by graphetti drawings on the walls in a hidden room within the level of the Companion Cube. At the end of the level, the main character is forced to euthanize the Companion Cube in a pit of fiery liquid metal. After which GLaDOS congratulates the main character and comments that she is the quickest of all test subjects to euthanize the Companion Cube.

At the end of Portal, the main character finally receives the cake in a brief party in which the Companion Cube is invited and surprisingly shows up.

The Companion Cube is your very best friend in the world, is male, cannot talk (though in the event that it does, Apeture Science strongly disregards listening to any of his suggestions), and is covered in hearts.
The Weighted Companion Cube would never hurt me.

Why? Why? Why? Why? Why?

An assortment of mostly ugly lesbian women and fat gay men who cannot get along well in normal gathering type atmospheres (bars, clubs....). They thriven e on their ability to control dogs. They put these poor creatures through Agility Training, Behaviour modifications, and will even hold tournaments in public areas to show off said skills. They call their pets their "children" and may even let them swim in their pools. They even go so far as to have award ceremonies for these types of things!!! They are often wart infested which is more of a become what you hang with - resembling German Sheppards in a way.
Hey - let's meet at the Companion Dog Club training center tonight!

Sure Kelly - are we still going to pretend we are sisters?

A special version of the Aperture Science Weighted Storage Cube. This cube is integral to your success.
Your Aperture Science Weighted Companion Cube will never threaten to stab you, and in fact cannot speak. If your Weighted Companion Cube does speak, please disregard its advice.

A defunct Wordpress blog from an arrested criminal that was a class of 1994, at Glenbard East who ran into classmate who eventually wrote the true crime yarn, The Cabbie Homicide -- as this one is a chronicled big name fan of the jam band Phish. Noted everyone else knows they are less than talented as they replaced The Grateful Dead in the 1990s. Their fanbase are known as phans as they also follow the act infamous for dumping 800 pounds of turdage on unsuspecting tourists. The light blue blog has appeal in underground heavy metal communities as being the counterpart to Fox News Channel and CBS News -- the candid life blogger with real reporting.

Known as a guilty by association in the Something Awful plagiarism incident that the goon got caught doing as the subject of "Pastor's Spouse" was also freight-trained for also covering up for it.
The light blue blog in 2014 had an investigative report of a classmate blogger behind the wordpress presence of The Sloping Companion as he later found that some were bitching about his fraud practices around the same time this came up. The wife at the time came and revealed that he knocked her up when she was just eighteen as he was a borderline pedophile -- he tried to sue the author of An Eye In Shadows for ten large, as this one threatened to cannibalize him like a Portillo's Hot Dog, in another blog entry the author took a barb implying if he wants to enjoy the taste of human meat, hands him a cleaver, suggests him to cut off his own limbs and cook them up in the back.
