Say what? - Avocado (pear)

"Pear-shaped fruit with dark green, leathery skin, a large stony seed, and greenish-yellow edible pulp. Also the topical American tree on which this fruit grows."

Originally the Aztecs called this fruit ahucatl after their word for testicle. This is may be partly due to the fruit's resemblance to a testicle, but also because it was supposedly believed to be an aphrodisiac.

To the Spaniards ahucatl sounded like avocado (=advocate, Spanish), and so the fruit came to Europe, via Spain, under that name. Avocado pears are also sometimes called Alligator pears. The etymology of this is far more obvious; the skin of these fruits is dark green, thick, leathery, and knobbly, rather like that of an alligator.
