When someone dislikes another individual in the workplace or elsewhere and decides to issue a "bless you" to everyone but that person when he or she sneezes, indicating a lack of worthiness and respectability.
"I don't think Jenna likes me anymore."
"Why not?"
"She gave the selective bless-you to everyone who sneezed in the office today but me, even though I sneezed three different times."
"Oh, that sucks."
