E.D.A (or EDA)
EDA is when a couple can't stop showing off their love online, and it's like they're trying to make everyone else feel bad. It's just too much.
A post that says, "We're forever.", but they're already fighting.
A tweet that says, "He's my everything.", while she's texting someone else.
A DM that says, "I'm so happy.", but they're both mad at each other.
