Kwyjibo, often misspelled as "kwijibo", is a difficult trick with two pops and a
dismount. To do kwyjibo, start with a trapeze pop up and quickly cross your throwhand over the other hand into the string, then roll it over to a 1.5 mount and cross your throwhand under landing in double or nothing finally just pop the yo-yo off and land into a trapeze.
History
Kwyjibo was invented in the late 1990s by Taylor Whitley. The name of the trick comes as a reference Simpson's episode Season 1, Episode 2 (Jan 14, 1990) "Bart the Genius", when the word "Kwyjibo" is invented by Bart to win a game of Scrabble. He defines Kwyjibo as 'A big, dumb, balding North American ape. With no chin and a short temper'. The name's misspelling origins came from an avid yo-yo forum user set his username to "kwijibo," spreading confusion every time he posted.
