My first horses name is Pistol and I showed him for 20 years as... Pistol. People said he was a farmpony and they couldn't believe I was showing him, but my old farmpony strutted his stuff!
I kind of like your horses name. I hate that some meaniehead has you feeling icky about it.
One of the definitions of Disposition is: Control over something
"Be a best friend, tell the truth, and overuse I love you
Go to work, do your best, don't outsmart your common sense
Never let your prayin knees get lazy
And love like crazy"
