- n. One who never laughs.
One minute you're learning that Sir Issac Newton chuckled only once in his life (scoffing at Euclidean geometry) and that the term for such people who don't laugh is 'agelast'; the next that the apparently nonsensical elephant jokes that were popular in the Sixties are believed to be racist in origin; the next how Bertrand Russell put down a heckler during one of his lectures on logic.
For example, an agelast is someone who never laughs.
