This is a person who, at a party, will be belligerently drunk, high, etc. This person will cause problems at a party, particularly party fouls (spilling things, knocking things over, etc). PDAs generally always make asses of themselves as parties; this is what they are known for. Many FYPs are PDAs.

Look at my new PDA!
Damn annoying cuddling,caressing,lovey-dovey smooching; actually any physical contact short the "fist-to-the-face" genre.Oh, right: in the presence of other living beings. Especially your friends! But animals count to, ya know. Spare the damn animals, you fiends! And the vegetation! LET GO!
