Slurm is a fictional soft drink in the Futurama multiverse. It is popular and highly addictive. It is Fry's favorite drink. It is widely seen throughout the universe. Slurm delivery trucks can be frequently spotted, including in the Futurama Opening Credits (shortly before the Planet Express Ship crashes into the billboard). The drink's slogan is 'It's Highly Addictive!' and its distribution is handled by Bureau of Soft Drinks, Tobacco, and Firearms, a parody of the Bureau of Alcohol, Tobacco, and Firearms (which is now known as Bureau of Alcohol, Tobacco, Firearms and Explosives).
Slurm has an active marketing campaign similar to the leading soft drinks of today. The campaign was fronted by Slurms McKenzie until his tragic death. The campaign uses an instrumental version of 'I've Got a Tan' by The Four Postmen. The Slurm posters seen throughout the episodes acted as one of the first clues to deciphering Alienese and have been compared to the Rosetta Stone by fans. Slurm also acts as a sponsor for two ladies competing in the Butterfly Derby.
In Fry & the Slurm Factory, Bender, Leela, and Fry find out that it's made from a secretion from the anus of the Wormulon Queen. Slurm is so addictive that even after Fry finds out what it's made of he can't stop drinking it and even the Slurm Queen appears to be addicted to it.
The queen can produce a highly concentrated super Slurm, that's even more addictive.
In "The Bots and the Bees", Fry gets addicted to Slurm Loco that is vended by Bev, drinking it non-stop until at first his urine turned green, then later started glowing green and making his skin radioactive.
