J & F

1. Slang used to describe a woman who is considered “high mileage,” meaning she has had many past relationships or partners.

2. The phrase comes from J & F, a used-car dealership known for selling high-mileage vehicles. The comparison humorously implies someone who has been “around a lot,” like a car with many miles on it.

“Bro, you taking her out again?”
“Man, I checked the Carfax… she’s a certified J & F.”
