In the spirit of the holidays, I was thinking about how you would say Eat! Drink! Be Merry! in Latin (or written as Eat, drink, and be merry!).
There are multiple words for each, but I'm not sure which best captures the feeling of this in English. To me, it's not just to literally eat, drink, and be happy, it's to do them in a celebratory context with others (except this year, of course). I also feel like it could be said in second person plural in addition to singular.
Per Joonas's post about a word least likely to mean drinking alcohol, bibere or potare both would work for drinking. I also think that laeta seems an easy choice for merry. I'm not sure about eating, though.
