Butter buddies 

Someone you eat butter with, typically in the sense that you are really hungry at a restaurant waiting for food and all you have is the butter from your bread and butter.

Jeffrey and Viola were at a restaurant and Jeffrey paid Viola $12 to eat four of the things of butter thus insuring a long lifetime of being butter buddies.
