Chuckle + snort, created by Lewis Carroll in Through the Looking Glass:
"'And hast thou slain the Jabberwock? / Come to my arms, my beamish boy! / O frabjous day! Callooh! Callay!' / He chortled in his joy."
Carroll was a great inventor of mashup words or, to use the word he coined, portmanteau words. However, not all of his new words caught on.
For example, slithy (slimy + lithe) and mimsy (miserable + flimsy), however delightful, never really made it out of his books.
