The phrase "make mincemeat of" is often used to describe a situation where someone has been thoroughly beaten or defeated. However, there are several antonyms that convey the opposite meaning. For example, "triumph over" or "conquer" signify a victory instead of a defeat. "Overcome," "subdue" and "prevail" are other antonyms that can be used to indicate a successful outcome. "Outwit," "outmatch," and "outplay" imply a superiority over someone or something. While "dominate," "vanquish," and "crush" are strong antonyms that suggest absolute control or domination over the other party. Ultimately, these antonyms convey a sense of success and achievement rather than defeat and failure.
