How to say "fucking" in Japanese

• ファッキン
  prenominal modifierThe English swearword taken straight into Japanese in katakana; it is vulgar slang and less common, and it carries the flavor of the English word rather than that of a native curse.
• ハメ
  noun (prefix), noun (suffix)This covers the sex-act sense: vulgar slang for screwing or having sex, essentially a crude noun for the deed itself. It is not the 'fucking' that works as a curse.
• ハメハメ
  noun, suru verb, transitive verbA doubled form of ハメ with the same vulgar sex-act meaning; the reduplication lends a lighter, almost jokey ring, so it reads as playful smut rather than a hard curse.
• マンコ
  noun, suru verbReally an extremely crude slur for the female genitals, so when it stands for the act it is by extension; as a way to say 'fucking' it is marginal and degrading.
• くそったれ
  no-adjective, na-adjectiveThe curse sense: 'fucking' as in 'damned' or 'bloody', an insult hurled at people or things; it has nothing to do with sex, being derogatory abuse rather than description.

For the sex act itself use 「ハメ」 or its doubled form 「ハメハメ」; for the curse meaning 'damned/bloody' use 「くそったれ」; 「ファッキン」 is the borrowed English swearword, and 「マンコ」 is really a crude anatomical slur.
