Frichen is a German dialect word that originally meant "to marry". Later, the definition was changed to "to strike". Many people in southern Germany still use the word, however it is no longer officially accepted as German. This is not what the word Frichen is remembered for, however. This word is responsible as the derivation of Fuck, which would later become the most common English cuss word as well as the most frequently mentioned F word, the biggest multi-definition F word and the only word in the English language to be known as the F word.
