To say: "Shines like a diamond in a goat's ass" is to provide high praise for something or someone. A harsh term, it is often used by men in the working trades. A star baseball player on a mediocre team could be said to "shine like a diamond in a goat's ass." Often, the phrase is used as a compliment for a really nice car or motorcycle. Ironically, it would not be appropriate to compliment a diamond ring or other jewelry with this phrase. (Body piercings excepted.)
1. That new chrome on your Harley-Davidson shines like a diamond in a goat's ass!
2. The ghost flames on your pickup truck make it shine like a diamond in a goat's ass.
3. Inappropriate usage: "Your engagement ring shines like a diamond in a goat's ass!" (That might get you bitch-slapped.)
Richard: "Camila please, I can't eat more, I am bloated like a goat ready for slaughter"
Camila: "Richard! Can you never go down on me without talking about slaughtering animals?"

This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
FRIEND A: "Did you just take a stealthie of me?"
FRIEND B (turning phone around): "no I was just using snapchat's new filter, see?"
