Why is someone who is considered an adult, or mature…

…now called “grown-ass”?

I am genuinely flummoxed by this, and absolutely have no idea what that slang even means…

…grown ass???

Are you serious?  What does it mean?

Oh, what it signifies is clear…a lot of language now days is mere emoting and signifying, and I decry that, it grieves me.

But I just heard someone who should know better refer to themselves as “grown-ass”.

*the effort to conceal derisive laughter was significant*
