Jimmies in NY?

[Carolina Jimenez-Marcos]

I moved from Texas to NY, where I've lived in Manhattan and Brooklyn for
the last three years. I had never heard of jimmies before the word appeared
on this list. Does anybody have a good idea of why they're called jimmies?

Another question, why do thieves jimmy a lock?
