Butter Up 

In prison, inmates lubricate their arsehole with butter before they see a visitor bringing them contraband. It ensures a comfortable insertion of said contraband.

Flanno is coming to visit me in an hour with some Meth. I better go butter up.

butter up session 

The exact opposite of a roast session

When you throwing compliments instead of roasts but with the same upbeat homie energy of a roast session

I was feeling down but the homies ran a butter up session to make me feel better
