Thanks for Quoting.

Used as a response when someone QFT's you on a forum.

When you eat dirt for the first time and leave your family to build a shack in the woods

A shortened / abbreviated 2 syllable version of the standard 'WTF' which is composed of 3 syllables. Most known for its use by Eric Cartman, a fictional character of a boy from the animated cartoon series South Park.

TFQ differs from WTF in such a way that TFQ is often used for repeated situations of amazement or disappointment, whereas WTF is most commonly used as the first way of expressing ones level of amazement (or disappointment).
