Japanese vulgarity does not map directly to English. Words like くそ are strong but may not carry the exact same weight as 'fucking'. Overusing them can sound unnatural or overly aggressive. Context and tone matter greatly.
For non-vulgar emphasis, use とても, すごく, or 非常に. For casual but not vulgar emphasis, 超, めっちゃ, or めちゃくちゃ are common. Reserve くそ and マジ for rough or slangy contexts.
If you want to sound angry and vulgar, くそ is the safest bet. For casual emphasis without strong vulgarity, use 超 or めちゃくちゃ. For sexual meanings, やる is the most direct vulgar verb, but セックスする is more common and less crude.
ちくしょう！なんでこうなるんだ。
Fucking hell! Why does this always happen?
