sounds just like 'thank you' but means 'fuck you' ; keeps up appearances and good form while saying exactly what you think ; a proper response to a left-handed compliment.

best used in combo w your toothiest grin. try it on your boss, mother-in-law, frenemies, teachers & snippy restaurant hostesses
