hippocrisy
"Do as I say, not as I do" behavior regarding large aquatic herbivores.
The term "hippocrisy" could also stand for ridiculous "talking outta both sides of your mouth" behavior that simulates how said lumbering "horse from the river" chooses to act --- for example, constantly badgering your kids to keep their clothes clean and pristine at all times, yet enjoying a good roll in the mud yourself.
