1: When your girlfriend notices the smell and taste of lotion on your dick. A man's dick is never suppose to smell like lilacs

2: The medical terminology for when a man places his penis into the microwave and sets the time to "popcorn setting", which in turn blows up the tip of his penis so that it resembles the lilac
