Grundle Bunnies 

Clumps of poop that get caught in your butt hair if one does not wipe well after pooping, usually causing an itchy sensation that screams "I NEED TO SHOWER......NOW."

"Damn dude, I need some scizzors to cut out these gigantic grundle bunnies so it does not itch anymore."

Grundle Bunnies 

When your toilet paper shreds while wiping your ass and you go do activities such as, running and playing sports...etc. and it rolls the paper into little fuzzy bunnies in the spot between your bizzalls and your nizut sizack...

That cheap ass toilet paper that she bought gave me a grip of grundle bunnies !!!
