What is 5 Dollar Shake?
Used in reference to the milkshake in Pulp Fiction purchased by Mrs. Mia Wallace, for something that's more expensive than its worth; even if its pretty damn decent.
"I don't know if that shake's worth five dollars but it's pretty damn good." - Vincent Vega.
"Holy shit dude, eight bucks for ice cream? What a 5 Dollar Shake."
