An angry exclamation. Ex:What the F--k!? or to tweeters, WTF!? .
A happy exclamation. Ex: I just won the Lotto!?Get the F--ck out! .
If something is broken. Ex: My computer has been F--ked up ever since I spilled water all over it. .
Telling someone to go away. Ex: F--ck you, I don't want to hear about it! .
As an adjective when you are angry/feel strongly about something. Ex: she was acting like a F--kin police officer the way she bossed us around. .
