Phlegm. The thicker, the more yellow, the more flavorful, the better...I wouldn’t recommend spreading it on your toast though.
The worst part of being sick is hacking up a mouthful of lung butter when you have no place to spit.

When an aircraft lands really nice and smooth without wobbling from side to side, braking too hard, making rapid turns and hitting the ground hard. To achieve this you need good piloting skills, so getting told you buttered the bread is a really nice thing.
Billy: There he comes!
Benny: Wow he absolutely buttered the bread
Billy: Yeah I know!
Michael: Watch as I butter the bread
Jimmy: Wow that landing was PERFECT!
Michael: Thank you

An Afro-American individual that has a thin or small penis. this individual of color thinks he is too big for his bed partner and lubes his penis with butter to make penetration easier while in reality it is an unpractical thing to do so, this is why he is called a butter nigger
That Brazillian dj, Lùcio I think he is called? That guy seems to think he is hot shit. He always brags he has a big dick, but my ex-girlfriend told me he is quite a butter nigger.
