Always. I try to pick witty and thought-provoking nicknames. I'm building a team right now with Hiero the Sigilyph (Hieroglyphics, both symbols and hip hop group), Laozi the Whiscash (named after the founder of Daoism), Winnfield the Bouffalant (Jules Winnfield of Pulp Fiction), Naja the Arbok (Naja is the genus for cobras), Hel the Froslass (Hel is the female ruler of the frozen underworld of Norse mythology), and Wheatley the Magneton (named after Wheatley from Portal 2 =P). To me, Pokemon is a game of creativity, with nicknaming being one of the many outlets for this attribute. It brings personality into a game that sometimes feels like tireless labor and number-crunching.
