Weird English

When you sign into Twitter it prompts:

What is happening?

This is WEIRD English. It sounds like a teacher walking into a disorderly classroom: What in the hell is HAPPENING around here????

Other socials use casual phrases like What’s on your mind?

Twitter reminds me of the standard prison greeting exchange in Mansfield:

What’s happening, man?
Ain’t nothing to it.

Pronounced:
Sapman?
Ennuntut.
