To cum really hard on someone. This word was created by an accidental typing of the word "practice" in a txt message with T9 languages turned on, creating the sentence, "Don't spaduge too hard." and becoming a running joke from there. Could be seen as a conjunction of "splooge" and "deluge" Pronounced "Spah-dooj"
"Dude, I hadn't cum in a few days so I totally spaduged all over Mike's ass."
