Public Display of Engineering

Like the universally despised PDA (Public Display of Affection) the PDE, or Public Display of Engineering involves two or more engineers engaged in a deeply technical, often hotly and loudly debated, all-encompasing discussion that while titillating and intensely enjoyable for those involved, is utterly cringe-worthy to behold.

Ugh, the Public Display of Engineering going on behind us is unbearable... Get a conference room, you two!
