What does PDA stand for?

Public displays of affection are a demonstration of physical affection and emotional connection between two people. Although quite often those witnessing such spectacles are inclined to shout out “Get a Room!” Showing public displays of affection depends on the upbringing of the couple about getting intimate out in the open. Some people will see it as the most natural thing in a relationship, while others will feel awkward when the topic is brought up and even more uncomfortable when the kissing or hand holding occurs without warning.
