oatsmobile
A smelly horse. Or a mule. Or a donkey. Or a burro. Basically any four-legged animal that eats oats and gets kicked in the nuts by kids.
My uncle's oatsmobile ran over my toe. I’m still limping.
That burro is my oatsmobile. It eats my breakfast and my dignity.
I called my donkey an oatsmobile. It stared at me like I owed it money.
