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.

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.

To pay ones respect.

Fast and Firm. In the fraternity world it means a term of brotherly love, like sincerely or dear when you are signing off on a letter or email.
