To take the day off work

A FERN is a nickname given to a nurse who works in emergency medicine, standing for "Fucking ER Nurse". FERNs are a special breed of nurses. They are rough, ornery, and house a level of sarcasm that can only be matched by the EMT allies. Their shifts are fueled by Bangs, 18 G needles, and their last fuck to give. They have no problem telling you that they do not give a flying fuck about the skin assessment of a healthy and ambulatory 28 year old, here for Cholecystitis". They also do not care that your are unhappy with a line in the AC (because the line was placed for the contrast dye used in the PE work-up, not your maintenance fluids). FERNs are best known for their resourcefulness, capability to run a code better than most Attendings, sick and dark sense of humor, and a cutthroat stare that could burn a hole straight through you.

Dirty, redneck, rabbit-like SEX in the woods!

A fat bum who sits around all day playing nothing but video games who thinks he is god and compares himself to singing birds. Who thinks he is intelligent when all beg to differ. Who cries and whines constantly. Who throws himself into walls in front of everyone and says he couldn't walk anymore because his heart was ripped to shreds. Who thinks he'll have a life after high school, when his mom still buys his clothes. Who will never know what brand clothing is. Who will stay a virgin until he is well over 40. Who will be on his death bed wishing he could go back and play Halo with his teenage friends.

Fern: A very potent fart,a very squeeky release.

The origin of Fern came from the actual sound that erupts from the anus
