Two Odd Etymologies

Nachos are named after a person, Ignacio “Nacho” Anaya, who owned a restaurant known as El Moderno in Piedras Negras, Mexico, across the border from Eagle Pass, Texas, in the early 1940s. Around 1943 he began serving fried tortilla chips topped with melted cheese and jalapeño peppers, calling the dish “Nacho’s Especiales.”

The taser’s name was inspired by a 1911 adventure book for boys, Tom Swift and his Electric Rifle, involving a rifle that fires electricity rather than bullets. The taser’s inventor, NASA scientist Jack Cover, thought this was an apt description of his own weapon, so he made an acronym of Tom Swift’s Electric Rifle.

Both origins are borne out by the Oxford English Dictionary.
