A stinky grimbus is a sexual act, where you buy a Hotwheels car of an American, yellow school bus. You ingest a ton of laxatives and insert the school bus inside your sphincter.
You then your partner to thrash your bum with his/her strap-on or meat sword until you shit yourself, ejecting shit inside yourself covering the school bus which is still inside you, in your liquidy doodoo. You then retrieve the school bus from your anus and find that it is now a dark brown instead if yellow and looking quite grim. A "grim-bus" and quite stinky

"Old-mate fell asleep first at the party, I think I'm gonna pump him full of laxatives and give him a stinky grimbus to wake him up."

When you’re in pain and you need to let your anger out in a fury you would yell “take a damn stinky”

I like to eat it it taste so good I recommend you try it just wait till a dog starts doing squats on the side of the road (don't worry it's just putting the ingredients together for the chocolate) and pick it up off the side of the road. It most likely will be wet and sticky but that's just because it needs time to set. Put it in a jar and poke holes on the top and refrigerate for 69-420 days. And that should be done! This is my favorite snack to gift to my friends. Also this also works as a facial cleanser. So yeah! Enjoy!
Oh! It's my friends birthday tomorrow, I'm going to give her some stinky caca! Because she loves chocolate!
