Did you know "Ba-a" can mean anything? It can mean "Thank you" or "Um, no." It can mean "Yippee!" or "Drat." It can even mean "Mmm." "Ba-a" is a more useful word than "Cheers" and "Fine" and "Y'all" all put together. "Ba-a" is the only word you'll ever need because it's not what you say in life, it's how you say it! If you were in a deserted island meadow and could only take one word, you should seriously consider taking "ba-a."
