A way of writing out the ever-so-popular Internet acronym "WTF" which stands for "What The Fuck". It is usually used to be funny, to exaggerate, or be very sarcastic. This method can also be used for any other acronym:

LOL - ell oh ell
ROFL - ARE OH EFF ELL
OMG - oh em gee

It has also been known that WTF has been pronounced like "wuh-tff" when people try say it like it's spelled, as they would say "Lawl" or "Rawffle" in lieu of LOL or ROFL.
Let's say Timmy and Johnny are playing Counter-Strike:
