When someone is so fat that it's hard to penetrate their ass/pussy, they are known as "solid butter" because they're too thick to spread.
Person 1: Ayy man I heard you fucked that fat chick last night. How was she?
Person 2: She was no good. That bitch was a solid butter.
Person 1: You mean she's fat from eating lots of butter?
Person 2: No, she's a solid butter because she's too thick to spread.

Get the warm buttermug. The act of lubricating a butthole (using butter or another oil) and sticking a finger in to achieve a boner ("the push-pop").
Matthias was in the mood for a snack so he grabbed the stick of butter out of the fridge and made a butter push-pop with Samantha.
