PDEA 

Public Display of Elderly Affection. It is nasty to think of old people kissing, why would you want to see it? Also referred to when your parents start to kiss in front of you.

Dude, when I saw that PDEA I was about to vomit.

PDEA 

Public Display of Elderly Affection

an extra gross version of PDA involving old people expressing their love

could be considered cute, but only if its really old people holding hands

-"ewwwwww do you see those 60 year olds making out over there?"
-"yeah, that's totally nasty PDEA!"
