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.

‘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.
