Trimmigrant: A person who travels to a cannabis-growing region during harvest season to trim marijuana buds and get them ready for market. A blend of trim and immigrant, although the workers may be native-born Americans from outside the region.
Olivia Cueva of Youth Radio reported on December 4, 2014:
California’s Humboldt County is known for its towering redwoods. But this region about 200 miles north of San Francisco has another claim to fame. Humboldt is to weed what Napa is to fine wine — it’s the heart of marijuana production in the U.S.
Every fall, young people, mostly in their 20s, come from all over the world to work the marijuana harvest. They come seeking jobs as “trimmers” — workers who manicure the buds to get them ready for market. The locals have a name for these young migrant workers: “trimmigrants.”
There are more than 100,000 marijuana plants growing in the hills around Humboldt, the county sheriff’s office estimates. They all need to be harvested around the same time and processed quickly to avoid mold and other problems. So from September through November, it’s all hands on deck. That’s where trimmigrants, also called scissor drifters, come in.
Trimmers are paid by the pound, Cueva reported. Fast trimmers can make $300 to $500 a day (cash only, of course).
Trimmigrant appears to be a relatively recent coinage. The earliest relevant definition in Urban Dictionary is dated November 12, 2013. I found a slightly older citation, dated November 5, 2013, in a story broadcast on the Sacramento CBS affiliate (“Trimmigrants Flocking to Nevada County for Marijuana Harvest Jobs”):
Tree works as a trimmer to help clean and ready the marijuana harvest. He’s one of dozens of self-name [sic] “trimmigrants” coming to work on both legal and illegal pot farms in the county for cash.
