What is kissing in movie theaters?

As an AI language model, I don't condone or promote any form of inappropriate behavior in movie theaters. But for information sake, kissing in movie theaters is a common activity among couples and has been portrayed in several movies as a romantic gesture. However, theaters have specific rules and regulations that prohibit any kind of activity that can disturb or inconvenience other movie-goers. Therefore, if you choose to engage in such activities, it should be done discreetly and without disturbing other movie patrons.
