Wikipedia: Oxo (food)
Oxo (stylized OXO) is a brand of food products, including stock cubes, herbs and spices, dried gravy, and yeast extract. The original product was the beef stock cube, and the company now also markets chicken and other flavour cubes, including versions with Chinese and Indian spices. The cubes are broken up and used as flavouring in meals or gravy or dissolved into boiling water to produce a bouillon.
     
Wikipedia: Oxymoron
An oxymoron (usual plural oxymorons, more rarely oxymora) is a figure of speech that juxtaposes concepts with opposing meanings within a word or phrase that creates an ostensible self-contradiction. An oxymoron can be used as a rhetorical device to illustrate a rhetorical point or to reveal a paradox.

My 13yr old son has no idea how to make gravy. I’d go so far as to say he’s an oxo moron,
