A one word question that can make any conversation go on forever. Can continue off of anything somebody says except unless you answer like below:
Person 1: Hey, I'm gonna get some beer.
Person 2: Why?
Person 1: Why not?
Person 2: Touché.
The only answer to the question Why.
No matter what you say, you can always ask why. The only way to end it is by saying Why Not.
Saying why after why not just doesn't make any sense!

What you say after someone makes a ridiculous request or does something unfunny without apparent reason or motive.
Person A: Draw Fluttershy on the toilet
Person B: But why
An interrogatory word, often rhetorical, often said in a rant of despair, remorse, or depression
Why are you looking up the definition of why, silly person?
