Dearest Dankshasta:
I've come to help you out a little. There's a place on the internet that I was told about long ago, it's called Merriam-Websters.com. That's
www.m-w.com, which is far easier to type than
www.dictionary.com But don't worry, I won't put you up to all that typing to find out the meaning of this word. No no, I'm a full service kinda gal, so here's everything you need to know about the world

Dear Faabio:
Thanks for not taking it too hard on the guy. We all have our off days. Of course, some more than others. Besides, it's cute how he speaks. I love those words kids make up all the time.
Best of luck.
