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."

A very pleasant girl who is one of a kind and everything about her is amazing other than the fact she stinks, unless you like that.

A PERSON IN THERE 50`S that asks like a big baby and craves attention. A Big Stinky will usually live alone, not have had sexual intercourse for many years and have delusions of grandeur but usually be unhygienic, still rely on there mother for money and to do there washing. Many BIG STINKYS will create a online person to hide their depression, usually pretending to have a unbeaten boxing record, claim to work when they live in their flat 24 hours a day 7 days a week. Any relationships they do have usually end due to hygiene issues

Two women have a staring contest while another woman will fart directly at their faces (mostly with her bare butt sticking out), the main point of the game is to not get distracted by the smell.
"Sally and Melissa were playing Stinky Staring the another day"
"Oh really? Who won?"
"Kathy, she ate too much Taco Bell for lunch"
"No wonder why the living room smells like rotten eggs"
