First used in Lithuania in the early 20th century, it has been connected to a colloquialism to describe people who have amassed great wealth. These patricians were known as "Golden Finger Kings"
"Yo, these bitches are bleeding my supply of Golden Fingers. Ain't a thirsty hoe here who don't want none of my fresh shit".
"20 Golden Fingers?!?!?... You'll be lucky to get 2"
John: Just think yourself lucky he didn't give you a goldenfist.
This can also be attributed to peeing in a urinal that is too high in relation to the position of the person's crotch.
I wish they had a pee-trough rather than these urinals so I wouldn't always get goldenfingers.
