Hmmm .... rings with corners? Sounds like just the thing for people with square fingers :)

It's neat to see mathematicians use humor sometimes in creating names for mathematical constructs. I found it in Rings of Operators by the great algebraist of the 20th century Irving Kaplansky, and I will add the reference to the entry. The term is also used by my former prof T. Y. Lam.

If anyone has come across a funny mathematical term, please share with the rest of us by creating an entry for it.

One favorite is "earthquake measure". See

Google has a lot of references on this one too.

Though it's not really a funny term, the term "adele" is another example of whimsical mathematical nomenclature...the term "idele" comes from the notion of generalizing an "ideal", and adeles were an additive version of ideles, hence the name.
