The one I associated best with were the Soldiers pissing their money away on expensive cars and booze. I was blessed when I joined back in the day because the Army didn't used to allow junior enlisted Soldiers to own cars or marry. Booze on the other hand...
I lived in a military barracks with a $20k motorcycle and a $1,500 gaming computer, so I can certainly relate to that post. I at least rode the bike as my main mode of transportation for six years before selling it for about half of what I paid.
Same thing I heard in my first full-time engineering job.
Don't get married, play the field (from older women engineers as well as men)
Buy a big truck or fast car.
Work hard, party harder, gym is for losers.
Fortunately my BS radar rejected/attenuated the spurious noise signals. I hate the 3rd person/order harmonics, sometimes 2nd too.
