You're at a party when you suddenly see your ex. You grab the nearest person and pretend to be dating him and they just happend to be very attractive.

"Act like you're my boyfriend, please.."

You whisper into the person's ear as he nods. The person suddenly grabs your chin and pulls you towards him as he presses his lips against yours, while your ex is watching.

The person pulls away from the kiss and look back down at you, as he says.

"hey babe, how are you?"
