(n.) A man who is on a woman's "safety list" of guys she has slept with in the past and who are not dangerous psychopaths or possessive and are halfway decent in bed. A woman will keep these men in her phone for situations when she is feeling horny but does not want to take her chances with someone new.
"Sarah and I broke up months ago but I'm still her safety D on occasional Friday nights."
