A sloppy circular shaped speck of shit plastered to the inside of the bowl given it's name due to its often striking resemblance to the mole that used to grace the right side of Spanish Pop singer Enrique Iglesias' face. (Too bad he got it removed). A man entering a bathroom to find an Enrique's mole down the toilet will often try to remove it from the bowl by directing his stream of piss at it.
Johnny - "Dude there's a piece of shit glued to the bowl in here that looks like Enrique's mole"
Richard - "Try and piss it off man!"
