what is a school PDA?

[Yakub]

i recently changed schools and i remember something that was called a pda at our old school and everone hated it. i looked it up and it looks like it stops people from kissing and hugging and someone even said slowdancing... my school allows a slow dance, and we can hug eachother freely but i still want to know what exactly a pda is, definition, all of that. so far it sounds really stupid.

A PDA is a public display of affection; it is an inappropriate display of affection that does not belong in a school. This basically means that it is against the rules to make out in public, etc.
