When you are with a couple and they either make-out, whisper, hug or stop in the middle of the street to do all that, the whole time. You need to tell "stop it with the EPDA!"
An Electronic Public Display of Affection. A public electronically mediated exchange, such as on Facebook, between a couple that evokes love or tenderness. Like regular PDAs, e-PDAs can potentially disgust everybody else not in the relationship.
A: Did you see Kristin's Facebook status update about how she had such a great time last night with Dan? Such an e-PDA.
B: Oh, and then Dan commented that he had a great time too. Ugh, get a room!
