ELI5: Explain Like I'm 5

Public display of affection

Public display of affection (PDA) is when two people show each other how much they like each other by holding hands, kissing, hugging, or cuddling in public - like in a restaurant or in a park where other people can see. Some people like to show their love for each other in public, while some people prefer to be more private. It's up to each couple to decide what they're most comfortable with.
