Spongebob Donkey Punch
The act of fellatio, when you do the bob and weave; then as he begins to climax, you punch him in the stomach, the esophagus, chomp on his weiner and finally a good punch in the square pants.

My girlfriend performed a spongebob donkey punch on me last night. It was the best blow job ever! It was so good I sharted and then she licked my ass crack, thus she performed a spongebob hershey kiss.
