E.D.A (or EDA)
EDA is when a couple posts so much love stuff online, it's like they're trying to drown everyone else in their sappiness. It’s super over the top.
A post with 10 pictures of them at the park.
A tweet that says, "I love you more than anything.", while they're fighting.
A DM that says, "We're perfect.", but they're still arguing.
