A popular metaphor created by the JETMILK publication signifying the amount of stimulation one is ready to receive. A reference to whether one can handle the jets in a hot tub being on or off.
JETS ON: Accepting of and open to a heightened amount of stimulation.
JETS OFF: Seeking little-to-no additional stimulation; a more chill vibe.
"Hey there's a new bar I wanted us to check out. Are you Jets On/Jets Off today?
"I'm feeling a little Jets Off maybe we can check it out tomorrow"
