Duck butter has been infamously claimed to be the 8th wonder of the world. The term "duck butter" was coined under the auspices of ducks hunters. Duck butter is the result of wearing hunting waders all day that leads to build up sweat, grime, gun powder, flatulent debris and the occasional pubic hair under ones scrotum traveling all the way back to the anus
"man, the only thing Robby has going for him in the duck blind is his uncontrollable build up of duck butter."

"After a long day of wearing waders out duck hunting, despite Chris's film of duck butter he still landed a Fupa queen."

"I think those Irish car bombs last night made my duck butter worse today"

Nothing in relation to the sweat glands on ones crotch or anus-y areas. Instead, Duck Butter is the secretion on Ducks wings and feathers so that they may still fly even after being in water.

Duckbutter differs from Smegma but is
pretty much the same. The smelly cheesed
odor that builds up between vagina as
well as the penis. Due to bad hygiene
mostly but still should be under control
by the tales I get from people who shower every 5 minutes. I pity those dudes but if you hafta you hafta-Rich
Smelly human problem!
