Verb. From Nahuatl.
“To make gulping sounds in the throat”
There are similar words to this in Nahuatl (spoken in Mexico) such as Koyöchöka, meaning ‘to make the sounds of a coyote.’ The suffix chöka is a verb meaning ‘to yell’ (and can also mean to make other varieties of sounds) hence why they are related to these words.
Interestingly enough, a word with a similar composition to the ones above, ïxtënchochöka, denotes the eyes becoming sore or irritated. Perhaps chöka is used in this context as a more figurative ‘yell from the eyes?’
