What is your favorite word? And the least favorite?

Not my favorite word but I find myself saying "shit" frequently throughout the day. I love the word "vacation" and hate the words "jury duty". Lol

My favourite word is "rainbow".
My least favourite is another word beginning with "r".

Favourite word “fuck”
Least favourite word “c””t

Imaginative. Wow! Also they put the word "wee" before everything over here. The number of times I've been tempted to say "Would a normal-sized credit card be okay?"!
