A reader came across the following sentence in an online advertisement for a local homeschool conference:
Enjoy a day chalk full of speakers and vendors while you are there!
She speculated that the misspelling of chalk for chock could have been intentional, given the nature of the conference, but decided that it was just an error and that the writer had intended to invite readers to a day chock-full of speakers and vendors.
The person who wrote the ad probably pronounces chalk /CHAWK/ to rhyme with rock /ROK/.
The expression chock-full means “filled so as to leave no vacant space; cram-full; stuffed full; full to suffocation.”
The expression has been in English with different spellings since the 15th century. Modern dictionaries, such as the OED and Merriam-Webster, give chock-full as the main form and choke-full as a variant.
The Ngram Viewer shows chock-full taking the lead in printed books in the 1830s and choke-full plunging toward flat-lining in the 20th century.
Not always spelled according to the dictionary standard (chock-full), the expression is popular in headlines and articles about various subjects:
Yesterday, NBC announced a schedule that will be chock full of brand new programming.
Those in attendance will get a hands-on preview of Little Orbit’s hot fall lineup chock full of popular franchises including Disney Planes.
