Pronounced "dat". Acronym for "Don't Ask, Don't Tell" used, generally in the military, to call someone out for a particular act of gayness. Most commonly used as a replacement for someone's name, but can also be used as a noun.
Hey DADT, nice pink Hollister shirt and pre-distressed jeans.
Dude, only a DADT would get a Mystic Tan.
