Evoking a similar feeling to this recent shopping list of anachronisms from xkcd, we enjoyed very much—via Web Curios—this catalogue of non-synonymous phrases whose constituent words are in fact close matches but convey as a whole very different meanings. 
One can toggle between family friendly and NSFW entries—a nice bit of wordplay, like crossword clues, and basis for a game—many of which were a challenge, a satisfying one at that, to work out, like Travel Expense vs Venture Capital, Lady Luck vs Misfortune, Fever Pitch vs Sick Note or Okay Boomer vs K-Pop. We think this sort of might be a case of applied collocation, resulting in a paronomasia or a case of double-entendre, but that’s best left to the expert cruciverbalists.
