"What Would Niel Patrick Harris Do?"

This is an abbreviation that asks the question, as stated above, what Niel Patrick Harris would do in x situation. So, basically, if something is going down, one would ask WWNPHD?
"Dude, look at the lifeguard! She's smokin'. Would you do her?"
"I don't know, but WWNPHD?"

"It's Godzilla!"
"Chill, man. WWNPHD?"

Luc: "I'm screwed."
Obi-Wan: "WWNPHD?"
Luc: "He'd use the Force!"
Obi-Wan: "You have learned well."
