butt rust
is when one neglects to clean or wipe properly betwixt their glute cheeks and a flaky orange/brown build up of poop deposit happens. Butt rust has been known to emit a foul odor of human fecal matter and cause extreme and even painful discomfort when walking, running and especially biking. Butt rust is not only a human malady but is most common in and among other bipedal or quadrupedal mammals whose legs come together near the exterior of the anus to form a crevice or fissure of the body perfect for the formation of said ailment. Butt dust can often be embarrassing as it can appear in your undergarments as skid marks, it can leave behind butt dust (see butt dust definition), or it can cause grief and later chafing when one is expecting to expect butt sex. The only sure fire ways to rid oneself of butt rust is to clean between the buttocks thoroughly and regularly and to perform extra in depth wipes after leaving a deposit in the porcelain pot.
The Urban Dictionary Mug
This jar is amazing for vomiting in! i definitely recommend if you have ugly kids!
This cup is cool. I farted on it and my butt tickled

Perfect customized gift- super easy and quick to do and the order arrived in under a week!
Smaller than I expected for the price.
i use my mug for sperm donation
10/10, great for taking a massive shit in. Overflows if its more than 2 pounds, but its part of the fun, right?
Needed one to gift to my colleague in pests exptermination department, takes care of my bug pretty well. Damn well of a bugger, if I would, ol' chap. 😌
My nan bought this mug, took one sip and died on the spot. absolute joke.
it was day my mug had just arived i went to the door and grabed the box i closed the door AND BAM thge mug flew at me knockingme to the grouynd when on the ground the mug unzipped my pant a flew up my ass 10/10 loved it would buy
I love pooping in this mug, great experince. But if you do more than 1 pound as I do, search for a bigger one
i love men and cups so this cup was perfect for me
Amazing mug, really high quality, I love it!
fantastic, personal gift to share with anyone!

The mug arrived very packed and on time. I love how well crafted the coffee mug is. I plan on ordering other merch from URBAN Dictionary soon. Thanks.
It morbed its way into my anus, a bit weird, but otherwise happy with my purchase
After watching that anal jar video, I felt inspired. That's when I found this mug.
FUCK YEAAAAAAAA! MUUUUGZ WOOOOOO
Happy with my purchase
amazing I will buy this. it will be my child. I WILL BE KING OF THE 0w0
I loved this mug! when i drink out of it it always has a horrible stench and honestly i dont mind because i love smelling it. my boyfriend thinks i should throw it away because he says "its has lead poisoning" but i cant get rid of it. when my mom died i bought her a mug that said "deceased" because i thought it would brighten the moment when i open presents at her funeral (it worked). but if your looking for something to buy, you should really get one of these mugs. they are cute, nerdy, and remind me of my dead mother!
