Talking about testicle…

The word avocado comes from the Spanish aguacate, which derives from the Nahuatl (Mexican) word āhuacatl [aːˈwakat͡ɬ],[40] which goes back to the proto-Aztecan *pa:wa.[41] In Molina’s Nahuatl dictionary “auacatl” is given also as the translation for compañón “testicle”,[42] and this has been taken up in popular culture where a frequent claim is that testicle was the word’s original meaning. This is not the case, as the original meaning can be reconstructed as “avocado” – rather the word seems to have been used in Nahuatl as a euphemism for “testicle”.[43][44][45]
