I hate the phrase "and all the trimmings." If the menu proclaims that a meal comes with "all the trimmings", I don't order it. It's pretentious in that down home sort of way, like a person who says "yee-ha". Don't ever say "yee-ha". Ever. "Y'all" is okay to say; that's a legitimate and very old contraction of plural "you". Granted, it does sound forced and artificial when it emerges from certain mouths, but that's true of many excellent words and phrases.
And what's worse than "all the trimmings"? Why, "all the trimmins", of course. The only thing more nauseating than a phoney baloney menu flourish calculatingly designed to convince people of authenticity is the same phrase deliberately misspelled to reflect pronunciation. Stop it!
