bacteria rancher

A person that, unknowingly or knowingly, ranches bacteria by not showering after football practice, weightlifting or any activity that involves heavy sweating.

It's the type of person that, for example, sweats while working out at the gym, then leaves without showering and goes to deposit all the sweat, filth and bacteria into their car seats where it can multiply and get stronger.

Girl 1: Lana is such a skank. She works out at the gym, sweats all over her clothes, and then gets in her car and sweats into the seats!

Girl 2: Oh gross, she is such a bacteria rancher!
