-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.
