Origin of Phrases - F
Fuck
Linguists believe that "fuck" comes from any of three words: the Middle English word "fucken," which meant "to strike, move quickly, penetrate;" the German word "ficken," which pretty much had the same meaning; or the Middle Dutch word "fokken," which meant "to strike, copulate with." Any way you look at it, the word can be traced back to between 1495 and 1505.
