When a guy/girl isnt interested in someone so they make themselves look bad on purpose to dissuade them from further pursuing them romantically.
Girl: Hey your cute! What do you do for a living?
Guy who's not interested: um.. I uhhhh.... I work for the local garbage company...
Girl: oh.... where do you live?
Guy who's not interested: I'm staying on this broken couch in my grandma's basement...
Girl: Gross.... wait are you vilibaiting me???
