What does Assnostic mean?

Assnostic meaning in Urban Dictionary

The spiritual belief which holds that asses, butts, booty, and junk trunks of all of the forms, colors, and sizes tend to be similarly intimately attractive. Strict assnostics will-worship butts regardless of what their age or problem, although a lot of assnostics apply their particular faith on just a finite scale (example. they worship asses of any shade, provided these are typically young and tiny, etc.)
