Grunderpants

Underwear soiled with fecal matter, having skid marks or filthy from bodily fluids such as semen, urine, vaginal secretions or ass sweat.

I just sharted. I’m gonna have to walk around with grunderpants all day.

She pulled her panties over my face. While expecting a fragrant experience, I got grunderpants and a big skid right across my nose.

I sniffed her grunderpants and it was a whiff of stank ass booty juice.

Grunder Trifecta

A Grunder Trifecta is the ultimate achievement of having the perfect combination of three bodily fluids stains in one's underwear a.k.a. Grunders at the same time. To achieve Grunder Trifecta status, one must have signficiant fecal, urine and semen stains in the underwear at any one given time (if male). If female, fecal, urine and vaginal discharge stains at any one given time.

The Grunder Trifecta stains can be created all at the same time which requires some significant skill with timing, sexual activity and dietary strategy. Most Grunder Trifectas are created over the course of several days or even weeks allowing the stains to form naturally over time which enhances their appearance and sometimes the quantity and thickness of the stains.

The Grunder Trifecta is often done as a precursor to creating a Grunder Quadfecta which adds a fourth element of smell to the underwear. The Grunder Quadfecta creates a strong allure when adding stench and aroma to the stains of a Grunder Trifecta.

While in the locker room after football practice, Roger noticed that Frank had been wearing the same Grunders for the past week. When confronted about the situation by Roger, Frank advised that he was just a shart stain away from having a perfect Grunder Trifecta and advised Roger that he was planning to go for the Grunder Quadfecta and anticipated after his date with Sonja the Village Bicycle, he expected that the aroma would permeate the locker room and all the team would embelish him with praise over his accomplishment.

Grunders

Underwear worn more than a 24 hour period of time by either a male or female. Underwear become Grunders after they are worn more than 24 hours or they are soiled and stained from urinary or anal leakage. The hallmark of turning your undies in to Grunders are those that are accentuated by skids and skid marks and mud marks.

Leroy was so behind in his laundry that he ran out of underwear. He ended up wearing the same pair for over two days. He finally did a load of whites after dropping skid marks in his Grunders.

grunder

Typically, a grunder (also known as; the georgia grunder) is performed by one female and many males. A large funnel is inserted into the anus of the female while she does a headstand, after which sweet tea is poured into the funnel. When the sweet tea is poured, and the funnel is removed...one of the males grabs the standard household plunger and places it over the anus of the female and plunges until the sweet tea is shot into the air like a fountain....after which the males participating open their mouths and try to drink from the fountain.

"Did you hear kelly is doin' a grunder tonight? Hot damn, where's my plunger!?"
