To perform an act, which seemed impossible just moments ago. Derives from a name of a famous illusionist "
Houdini" and a expression "
Pulling something out of your ass", which describes simular action.
ex. 1. "Hej dude! Writing this code in such a hurry must have been a real pulldini for you!"
ex. 2. "He performed a pulldini when LCD projector on his presentation failed - somehow he managed to get 400 copies of text in minutes and distributed them around."
