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!!!
