Refers to publicly-voiced derisive/uncomplimentary remarks/details ("sass") made about someone regarding his less-than-perfect-looking posterior ("ass").
(a prime example of character ass-sass-ination, from an old "Blondie" cartoon) Mrs. Dithers: In my younger days, I had quite a following.
Mr. Dithers: And she still does, heh, heh, heh... (cheekily placing his hand beside his mouth as if to prevent his wife from hearing his "aside" remark) ...but her dress-maker keeps it well-hidden!
Dagwood (staring down at Mr. Dithers' prostrate figure that's sprawled untidily on the floor as his irately-unamused wife stomps off in a huff): Do you see stars, Boss?
Mr. Dithers: Stars?!?? I can see the entire AURORA BOREALIS!!!

Get the Sassmug. Unwarranted criticism from your Uber driver about where you waited to be picked up, your luggage size, your desire for air conditioning or how loudly you slammed the door.
When a got in the car the driver gave me a bunch of Uber sass because he had to cross the street to pick me up.
