Every since I did my first Nuzlocke I simply must name them. It once took me a full 5 minutes of thinking before I found an acceptable name. I can't remember using that pokemon though... --- Newbie PKMN Trainer: 0132-8070-8825 BLACK
Almost never, I just don't get attached to them like some people do. The only times I remember naming them was when I was capturing them for completion and they were a particular pain in the ass, so I would give them degrading or hilarious names. --- "They don't think it be like it is, but it do." - Oscar Gamble Should have.

I almost always give my Pokemon nicknames, unless they're Legendaries. In that case, I'll simply name them what they are (Latios would be named Latios, for example). --- Sab_Liath defeats Topic! Gains 89 EXP! Learns Magma Drill!
