You were chilling at a party with your boyfriend before I left to use the bathroom for a few moments. While he’s gone, a guy comes up to you and starts talking to you. As the conversation progresses, you begin to realize that he’s flirting with you. Before you can react, your boyfriend comes behind the guy and grips his shoulder tightly, giving him a hostile smile.

“What are you doing, dude?” He says low and intimidatingly into the guy’s ear.
