Crusty and dried on shit on your butt cheeks resulting from shitting in the middle of the night, and passing out on the toilet before being able to wipe your ass.
I passed out on the toilet last night and woke up with my ass cheeks covered in sphincter dust.
I need to take a shower to wash off this sphincter dust from last night.
When instead of wiping your ass after shitting, you push your penis through your legs and piss on your asshole, successfully cleaning yourself from left-over feces residue in your ass-crack
A sphinctard is the all too common combination of Asshole and Retard. A typical sphinctard will fuck things up, lose or misplace his things, make a lot of mistakes and then actively, even agressively, blame others for all of it. A sphinctard will NEVER accept blame for anything, no matter how obvious it is to others that the sphinctards problems are of his own making. Sphinctards always have a feeling of entitlement, usually the product of rich parents that totally spoiled them when they were growing up. Sphinctards are ALWAYS cheap. Sphinctards usually have few friends, but sometimes have suprisingly good looking looking girlfriends. The girlfriends ALWAYS have a very low self-esteem because they are the only people that will put up with a sphinctard for very long. Sphinctard's girlfiends usually split the tab or pick up the whole thing.
1. That Sphinctard borrowed, then crashed his sisters car, then blamed her for not having better quality tires on it.
2. The Sphinctard forgot where he left his toolbelt, then blamed the firstguy he saw for stealing it.
3. The Sphinctard told his girlfirend that she had to pay the restaurant check because his steak was a bit overcooked and he shouldn't have to pay for a meal he didn't enjoy.
