I like the cattle whipcracker explanation better.
I think the negro,s got the term from watching the Howdy doody show
Clarabelle the clown on cattle drives whipping the schit outta unruly cows that didnt wanna work and schitt.


And that explanation is also the one to agree with cause mannlicher has more post than both of you combined and been here longer than slumlord and fester combined.

Cracker:
Clown on a dumb tv show that used ta whip da chyt outta cows
( specially the black ones)
