Principal English Translation: 

something that burns the mouth, such as hot peppers (see Molina); misery, tribulation, affliction (see attestations); also, a person's name, attested as male, Cococ

Alonso de Molina: 

cococ. cosa que quema y abrasa la boca, assi como el axi, o pimienta. &c.
Alonso de Molina, Vocabulario en lengua castellana y mexicana y mexicana y castellana, 1571, part 2, Nahuatl to Spanish, f. 23v. col. 1. Thanks to Joe Campbell for providing the transcription.

Frances Karttunen: 

COCOC something that stings the mouth / cosa que quema y abrasa la boca, así como el ají o pimienta, etc, (M) [(1)Cf.127r,(1)Tp.115,(3)Zp.98,145,(1)Xp.32] . C specifically gives both vowels short and contrast this with COCŌC ‘affliction.’ But only the single attestation in C is in accord with this contrast. ALL the other attestations have a long vowel in the second syllable. Z has a derived noun COCŌYĀLIZ ‘piquancy’ which is deviant as a derivation from either COCOĀ or COCOY(A). See COCO-TL, COCOĀ.
