PDA
Public Display of Affection. When people display "affection" in the viscinity of other people. Hugging or more, usually. Why does everyone think it's gross or that people shouldn't do it? I don't know. They obviously don't believe in love. People shouldn't have to hide their love.
Girl 1: Eww that's a PDA right there! Get a room!!!
Girl 2: Shut up, it's romantic.
