A working laptop or netbook computer with noticeable and/or potentially compromising physical damage. ie; cracked casing, partially damaged screen, a missing panel or button(s). Usually an older or obsolete model.
My cracktop is missing the Fn key and the screen is held in with stickers, but it still works well enough to check email.
Acronym for National Strategy for Trusted Identities. Pronounced the same as "nasty".
