Grammar question Why not plus ing-form?

[Blacky]

Can you say : Why not going home now?

[Conchita]

Welcome, Blacky!

As far as I know, 'why not + -ing is not good English. But you can say: "Why not go home now?".

[Prezbucky]

"Why not go home now?" is a suggestion. You're really saying, "Let's go home now."

It is possible that the question is not rhetorical... that the asker is actually wanting reasons for not going home. In practice, though, it's usually a plea to leave.

"Why aren't we going home now?" or "Why aren't we going (leaving) now?" is just about the same -- let's get out of here!
