‘Duck Butter’ is the greasy, sweaty residue that builds up between the nutsack and inner thigh whilst wearing chest waders all day during 25+degrees on summer wildfowling hunt.
“Bloody hell Bob, that was a tough day out on the marsh, the old ‘duck butter’ is kicking up a bit.”

A juicy gurgling, squirtling, greasy fart, the kind you need to check your drawers after releasing, to make sure it was ONLY a fart. The sound of this type of fart is similar to an octave on a trombone.

The sweat right between a mans testicle sac and leg that has condensed and gathered lint, hair, dirt etc... Usually the stinkiest/manliest part of the mans body. Although it is gross, women will always be attracted to it.

Any type of mortuary grade moisturizer. Usually white or flesh colored. Used to prevent dehydration of a corpses skin.
After embalming a body, make sure to slather copious amounts of duck butter to the face and hands to prevent tanning or discoloration.
