How can I replace the most popular cuss words with words which don't sound overly deliberately euphemistic and outright childish? [closed]

See minced oath on Wikipedia:

A minced oath is a euphemistic expression formed by misspelling, mispronouncing, or replacing a part of a profane, blasphemous, or taboo term to reduce the original term's objectionable characteristics. Some examples include "gosh" (for God), "crumbs" (for Christ), "crikey" (for Christ kill me), "for crying out loud" (for Christ's sake), "darn" or "dang" (for damn), "doggone" or "gosh darn" (for goddamn), "cor blimey" (for "God blind me"), "heck" (for hell), "gee", "jeez", "jeepers", or "Jiminy Cricket" (for Jesus Christ), "feck". "fudge", "frick", "fork", "flip" or "eff" (for fuck).

Note I am not saying how accurate the above examples are, I'm merely quoting directly from Wikipedia.

Wiktionary also has some examples of minced oaths.

• cheese and rice for Jesus Christ
• gosh for God
• geez for Jesus

etc.
