Butthole Dickmole occurs when one is engaged in sexual intercourse of the anus and upon withdrawal of the penis, notices that there is a smidgen of poo on the head of his penis bearing much resemblence to a mole. If your name happens to be Spencer, you may panic in fear that your fuckbuddy might see the speck of shit which would cause severe awkwardness so you decide to ingest the mole-resembling dot of shit and then comment to your friends that it didnt even have a taste. "very bland"
