Funning is a word you use when someone has asked you "Are you having fun?" or something annoying while you are trying to enjoy something. Instead of just saying "Yes, I am having fun." You can say: "I'm funning!" and then the person who asked will now begin to ask people "Are you funning?" This word is for convenience, so use it.
The act of not so subtly one upping someone while casually mentioning you are better than them.
"I got our teacher a good luck basket for the beginning of the year."
"I bought the administration, past teachers, and current teachers all a gift card for lunch and a little goodie, just as a little welcome back."
"Are you flynning me?"
