The anus. Derived from a certain scene in Spongebob where two characters tried to shove a coin up a seahorse's ass, thinking it was a coin slot for a kiddie ride. See Chocolate starfish or Leather cheerio.
My rubber coin slot is itchy but I can't scratch it or else my hand will smell like ass.
Term describing the top of the ass crack when it can be seen protuding from low worn pants. Usually associated with skanky old fat men and slutty girls trying to get some.
result of one who has not mastered the art of wiping ones own ass correctly; characterized by an ass crack full of shit stains; often results in skid marked under garments, rancid fecal odor and an itchy booty hole
When defecating, I prefer to clean me crap crack with wet wipes, this - in turn - will alleviate me from sporting a rusty coin slot....which, I believe is generally frowned upon
