When 2 guys stick their dicks in a woman's ears (1 in each) and then cum so it spurts back and covers their respective cocks. After this the men spread their cum covered cocks on the girl's tits like spreading butter on a buttery (this is most commonly used in Scotland)
Dave - "you see that bird over there by the bar?"
Jackson - "yeah, what about her?"
Dave - "Let's give her a double buttery"
Jackson - "sounds good"
