Mr. Fitness Instructor

That guy who is not in very good shape, yet feels the need to criticize everyone on their form and the amount of reps someone does during a specific exercise.

Guy 1: Yo dude, your curling form is horrible. Straighten your arms and increase your weight.

Guy 2: STFU Mr. Fitness Instructor. Since when did you become an expert this shit?

Police gym instructor

A failed police officer than cannot make it as a regular police officer. A position in which the officer can do nothing and still brag about being on the force.
Typically these officers have not made a collar in many (many) years.

Pete was so inept at being on the street they assigned him as a police gym instructor.

Marine Corps Drill Instructor

Hard-bitten, short-tempered, deep-voiced, screaming, seemingly-psychotic, unpatronizing, impatient, deeply-devoted and fully-dedicated Marine NCO who must work his magic on Momma's Boy --- who possesses eighteen years of cumulative selfishness and "Me-ism" --- in order to begin the makings of a disciplined Marine who will stand and fight when every inborn instinct tells him to run, and who, himself, will one day be a Drill Instructor to whom other youngsters "surrender body and spirit to harsh instructors and receive a soul."

The recruit went into the duty and stated, "This recruit was lied to by his recruiter, he was told he could go back home if he didn't like it here". The Marine Corps Drill Instructor replied "I don't give a fuck what your recruiter said, the only way your getting off my Depot is to walk across that parade deck on graduation day, or get dragged out of this bitch in a bodybag".

Embry Riddle Flight Instructor

A poor, pathetic breed of person that only holds his or her job in order to build flight time for hopes of obtaining a future airline job in order to be lazy as hell and still make a lot of money.

They are often deceitful and take full advantage of students by overcharging them or using them to fit their schedule while only teaching them the bare minimum. This type of person is easily recognized by an over inflated ego and stripes on each shoulder to fake that they actually fly a significant aircraft.

Jaime is a little bleached brunette, pimpette embry riddle flight instructor who lies to her students and uses them to fit her time and financial needs while faking that she actually cares about them.

Line Dance Instructor/Whore

This applies to any skanky girl who lives in a city who thinks she is "country". She may have a bit more rythm than her non instructor counterparts. Her main purpose in life is to mooch free crappy beer off guys who have girlfriends or wives. Also an evil temptress.

The Line Dance Instructor/Whore slept with five guys tonight.
