Someone who ignores your existence in public but is nice enough to keep you interested in them. while also confusing you as to if you like them as a romantic interest, a friend or an arch enemy.
David walked up to me and didn't say anything. That asshole just texted me.
An attractive man who is indecisive, flirty, makes you feel bad for wanting to hate them because you they're actually nice people, and who is unavoidable because of the mutual friends that you share.
Oh, David said hi to me today. What a giant fuckface.
