Quite literally, an overdose of "izzles" in a given sentence. Often, the suffix will be used to the point of rendering the statement unintelligible and hilarious. While Snoop Dog has honed the craft into a precise science, "overdizzling" is found in words that ought not be "izzled" in the first place. A safe rule to follow is that if the word is more than 75% "izzle," then it has been "overdizzled."
Ivo overdizzled last night when he spouted: "Yo dude, be shizzle to pizzle that wizzle on urbizzle dicizzle befizzle the credizzle goes to some asshizzle!"
Snoop Dogg for nerd. Following his pattern of swapping out the last syllable with -izzle or just appending -izzle to the whole word or just appending -izzle to only the first syllable of the original word, to make it swag. Popularly used by Howard Wolowitz on The Big Bang Theory.
