F 

A way to show the utmost form of respect during an unfortunate or tragic event. This form of flattery stems from the world of gamers. "Press F to pay respects" is the caption in a scene that occurs at a funeral in Call of Duty: Advanced Warfare. See oof for a less formal method of condolences.

F- 

The legendary grade of myth given by teachers to those students demonstrating a level of suck beyond imaginable. Acquiring an F minus for a grade is such a feat beyond the norm that this student must be beyond hope.

Such a feat as acquiring an F- is not an easy gain, and the everyday slacker will just not do. To obtain such a legendary grade upon your classroom input, one must work hard and put in thousands upon thousands of samples of ignorance while simultaneously putting in time unworthy of class participation points such as the classic "A for effort".
In most cases, this grade is so beyond fail that it equals win.

Teacher: I called upon you to do your presentation, so you walked to the front of class, sat in my valuable teachers' desk that I paid for with my own money, and managed to break it. Not to mention this is chemistry class, NOT geometry, and doing a demonstration on finding the area of a Pokeball will get you nowhere in life. F-.

-f

-f is used as a non-professional shorthand form of the word fuck. of fucking. It does not generally refer to the sexual act. Instead, this is simply a written profanity; one which by its short nature is less obtrusive and does not leap out of the texture as does the actual word fuck

It is built ugly style, so we can get the -f on with it, and so that we can change things easily.

"Oh no I totally -f ed it up" said the Gandalf the greybeard of CERN laboratories while pacing up and down paying homage to the particle accelerator.
