Sea-Hagging
Performing unprovoked, calculated acts of malice or cold exclusion against someone while pretending to be polite. The adult equivalent of standard mean-girl tactics, carried out by someone whose personality is as toxic as sulfur.
"She pretended to be nice to my face, but then spent the rest of the night sea-hagging behind my back to everyone in the room."
