The process of replacing innocuous words in popular media with another (sometimes) related sexual term. The most widespread example of said process is the replacing of "wand" with "wang" in the
Harry Potter books. Another widely known instance is replacing "fairy" with "penis" and "
Great Deku Tree" with "vagina" in
The Legend of Zelda: Ocarina of Time.
"Harry looked down at his own wang. he could see finger marks
all over it. He gathered a fistful of robe from his knee and tried to rub it clean surreptitiously. Several gold sparks shot out the end of it. Fleur gave him a very patronizing look, and he desisted." (A passage after undergoing wangifying)
"Kathryn spent
Saturday night wangifying the 6th
Harry Potter book instead of doing her homework."
