When you are trying to type the word fun but you mess up

When you are speaking and trying to talk about something "fun" but your mouth farts
"This is going to be so flun!"
"WTF is flun lol"
"Oops, gtg die in a hole"

Get the flun mug.
When your stomach is full after eating a triple burger with extra large fries, but you need to run to catch the last bus.

-Full stomach running.
Try to keep your food in while flunning, Samantha... You can breathe when we get in the tram

A toy gun that can’t kill people
Little Billy shot daddy Billy. Little Billy is upset because he used a flun and daddy Billy is still alive.
