What is rhopalic text?  Well, here’s a nice example of a piece:-

“I do not know where family doctors acquired illegibly perplexing handwriting; nevertheless, extraordinary pharmaceutical intellectuality, counterbalancing indecipherability, transcendentalises intercommunications’ incomprehensibleness.”

Rhopalic describes text in which each word contains one more letter or syllable than the one preceding it.  This text starts with 1 letter, then 2, then 3 and so on…. Clever stuff.
