A person in the military who knows he or she cannot function outside a military environment. Hence, they remain in the military for life. Even after retirement, a lifer will remain in the type of social structure fostered by military retirees. In other words, a group whose authoritarian characteristics can only exist around military people. "Lifer" also describes a person who is imprisoned for life, either by sentencing or, as with the military types, by choice.
"Randy is a real gung-ho lifer. If he tried to act that way in the civilian world, they'd get rid of him in a heartbeat"

A person who doesn’t have goals or at least doesn’t make it a priority to fulfill their goals. These people include stay at home housewives, people who live with their parents, minimum wage workers, trust funders, and sometimes college graduates who choose to be over qualified for a job, such as mall jobs, customer service, ect… These people can often have children before marriage for a sense of purpose, substance abuse problems, blame minimum wage for being too low.
What does your friend's wife do for work? She doesn’t work or go to school, she just walks around with a selfie stick and takes pictures of her child and complains about animals in captivity on Facebook. She gets a shit ton of likes for some reason. I don't know how she can live just being a lifer.

My manager at Starbucks takes his job too seriously, he got his G.E.D and thinks it’s the most important job on the earth and I’m his minion. It sucks working with a lifer.

This guy my sister has been seeing is a Lifer. has been working as a lifty at Sierra at Tahoe for 10 years now and is constantly snap-chatting while driving, he doesn’t have a deep personality and probably will spend his whole life working at a ski resort.

My friend is a lifer. He got his first D.U.I at 20. He goes and spends his paycheck at the Casinos every Friday and Saturday night to try and make a buck or pick up on tourists in town for the weekend. He often goes to night clubs and plays slots alone.

What did your sister do when she graduated University of Organ? She got a job at lululemon, she’ll probably try and marry a man who is well off and continue working there the rest of her life. She's such a lifer
