expression used when a person doesn´t know or forgot something typical, classic or trending. Mostly like an ignorant person that doesn´t know universal history, breaking news, mainstream facts, etc. Usually air heads deserve cultural slaps.
Example 1: It´s incredible that my boyfriend doesn´t know in what continent Egypt is, pff cultural slap!
Example 2: Are you kidding? Why have you never seen the end of Titanic? Cultural slap.
