Now I must squeak about the deplorable massacre of the English language being perputrated upon us by the illiterate bastards infesting this board.
"udder devastation."
The expression is "utter devastation"
"udders" are cow nipples.
"continues to ... placates our existence"
Placate means to pacify and calm. I believe the expression you are grasping for is "Plauge our existence".
"infernal gangbangs"
"infernal" means underground or hellish/diabolical. It makes more sense to say "eternal", as in to mean never ending gangbangs.
The appropriate word for your problem is Malapropism, which is the use of a word inappropriately. This word was coined after the humorous fictional character Mrs. Malaprop in Sheridan's comedy The Rivals.
Her name comes from the French mal à propos, which means inappropriate. The self-educated Mrs. Malaprop was always substituting a similar-sounding word for the word that she intended to use.
