Run up to him and give him a full on kiss with no warning

From Create Your Own Story

His eyes widen and he proceeds to open his mouth in an attempt to speak. Instead, however, you slip your tongue in his mouth in an attempt to seduce him. He stops trying to escape your kiss and kisses you back. You kiss for a good five minutes before you hear a scream- Get off my boyfriend you bitch! Oops. You forgot he had a girlfriend. She pulls you off of him and slaps him across the face. Then she turns to you. This can't be good. "And you" she says "I should snap your neck, you little bitch. But I won't yet. I'll make life for you a living hell. You'll wish for death, in fact, I'll be the one to put you in your casket, mark my words". She then proceeds to give you the finger and head on her way.
