also known as the taint, the duck butter brewery is the land that sits between a person's brown eye and ball sack. It naturally produces duck butter.

dude 2: my brother, that's just another productive session at the duck butter brewery.

In the true fashion of the Dirty Sanchez, you wipe the sweat and funk off of your cock and balls; then wipe said funk underneath an unexpecting guy or girl's nose, but above the upper lip.

When, during a fight ( play or real), one person reaches down their pants and retrieves a copius amount of duck butter, then bitch slaps the other person in the argument. Not only did you just get slapped, but SURPRISE, now your face smells like duck butter.
My girl wouldn't quit messing with me, so finally I just pinned her down a gave her an extra greasy duck butter surprise. She said her face stunk for 2 hours.

When two (ugly) people (male&female) have sex, and a gelatin/butter substance is made between the two of them. Usually disgusting and smelly, and leaves a snail trail like substance on sheets. If they do not separate, the duck butter will harden and cause trouble for the both of them.
"Ewww, they are going to make Duck Butter together"
"They are so ugly they make duk butter, when they have sex." - A random uncle.
"Lets go make some duck butter!"
