A sexual act named after a favorite Ice cream flavor, where the male leaves a turd in a toilet. Then later in the evening performs doggy style on his partner in that same bathroom in front of the toilet, lid down. Then before he releases he opens the lid and shoves his partners face into the toilet and yells "fudnickle".
