It means you asking someone what is the temperature outside or inside. Can be "What's the C" for Celsius areas. (Or even K, if you wanted.)

Response ends with the actual temp. but you just say the number and 'F' at the end.

Get the What's the F? mug.
Short for 'what the fuck' when one is found to be around adults/children or people who are bound to be offended by the usage of the word 'fuck'.

(but not necessarily saying the letter f, but the pronounciation of it; like when you hit the breaks before you hit the tree. and in this case, you pause before you extend your cursings.)

Get the What the f*** happened to the floor mug.
Taken from "Bloody Hell", (see in this dictionary), this phrase emphasizes a double fuck without actually using the word once and therefore, appropriate to say in public.

So in that sense, it's like saying, "What the fuck?" but twice, "What the bloody F?!"
