The f-word is extremely versatile. You can use it as a noun, an adjective and even an adverb. Plenty of movies make good use of the swear, and now you can see it in one convenient mashup -- the inevitable 100 Best F-cks in Movies, Part 2 (you can check out part one, which was posted earlier this year, here). Just like that first video, this 14-minute clip is organized by use. For example, if you want to see the f-word used as a question, go to 3:43 in the video; as a substitute for mess up/screw up, head to the 4:45 mark; and, for our personal favorite, the multiple use of the f-word, that starts at 11:27.
This goes without saying, but this clip is very NSFW. If you want to see the full list of films used in the video, you can check it out here. Preferably when you're in the comfort of your own home.
