The phrase "lost 'em" is a shortened version of the phrase "I lost my chromosomes" which is a phrase used to express disbelief or to express the stupidity of others.

The phrase's origin can be traced back to Fullerton, a city in Orange County, California, and to the years 2016 and 2017 when it was first mentioned in text. The originator of the phrase has been speculated to be a particular Gabriel Lariz, a local student in the area. There is some debate over who truly invented the colloquialism, as it rose through popularity and usage through many others, but after a few interviews with Fullerton locals, most agree that Lariz is the originator of the phrase. The phrase rose in popularity through its usage by many of Lariz's acquaintances, most notably those in the notorious Wilshire Block gang and many of his fellow classmates. The phrase began to spread from school to school in the area and has been uttered in other cities in Orange County.
