An "F hole" is the curlicued hole cut into the front of a stringed instrument.
There was also a Seattle-area rock band in the 1980s called "The F Holes" which gave a lot of people the wrong idea.

All violins, violas, cellos and double basses have 2 holes either side of their bridge. These are, in fact, the instruments 'pair' of vaginas.
Dude, what are f holes?

F holes are it's pair of vaginas. That's how string instrumets mate. Endpin > either of the vaginas.
