your sitting at a party enjoying your drink with friends and chit chatting when you catch a guy staring at you seriously and blinklessly,sipping on his alcohol.you look back at your friends and felt a wave of chill and fear runs down your spine he's wearing all black, black shirt, tie, pants, and shoes, looking like a boss or a mafia

moves his head downward slow as a gesture for you to come near, still blinkless stare

will you go? ignore? or tell your guy friends sitting next to you?
