A "crusty rudder," not to be confused with a Dutch rudder, describes the sexual act of a male squatting on a female and farting with enough force to produce an audible sound and send tremors through the female's face. In most cases the female contracts conjunctivitis.
Pharmasist: "Kirsten, how may I help you?"
Kirsten: "I need antibiotics for my conjunctivitis."
Pharmasist: "Oh dear! How did this happen, again!?"
Kirsten: "You know how Chris likes those crusty rudder sessions..."

Get the Crusty ruddermug. by Spfld Rat Mark December 17, 2011
Get the Crusty hosebagmug. A thicc girl with thunder thighs, and a crusty asshole that has a heavy stench of dry shit. The smell is much more potent when the girl has swamp ass and the sweat moisturizes the shit. Girls like this have poor hygiene, and typically don't shower in the morning.
Guy #1: Damn dude I fucked this chubby girl last night, but I couldn't finish cuz it was so hard to put my dick in and her asscrack smelled horrible!
Guy #2: Damn dude I can't believe you fucked a crusty thunder.

"Boy, you pissed me the fuck off you better not leave your house or I'm going to give you some crusty sleeves."

Get the Crusty Sleevemug. When one ejaculates a significant enough quantity within their pants so as to build up a thick shell around their junk that acts as a biodegradable, homemade, and shock-resistant cup.
