PDA meaning in Messaging ?

Public displays of affection (PDA) are acts of physical intimacy in the view of others. What is an acceptable display of affection varies with respect to culture and context.

Some organizations have rules limiting or prohibiting public displays of affection. Displays of affection in a public place, such as the street, are more likely to be objected to, than similar practices in a private place with only people from a similar cultural background present.

Physical affection has been defined as "any touch intended to arouse feelings of love in the giver and/or the recipient."
