minced oath

A minced oath, also known as a pseudo-profanity, is an expression based on a profanity which has been altered to reduce or remove the disagreeable or objectionable characteristics of the original expression; for example, "gosh" used instead of "God," "darn" instead of "damn","heck" instead of "hell" and "freaking" instead of "fucking". Nearly all profanities have minced variants; the words that are most taboo give rise to the most.

(n.) = blasfemia eufemística
Ex: Use of a minced oath in the place of something ordinarily considered blasphemous is still blasphemous as the minced oath is merely a euphemism for the same thing.
