Abbreviation for Neil's Per Hour, used to describe how many times someone has seen Neil Patrick Harris within a certain period of time.
"Me and Gerjan were watching the Harold and Kumar movies yesterday on TV, and then the new Old Spice commercial came on... clocked us at 3 NPH."

"Bah, we clocked at 6NPH's when we had a Doogie Howser marathon last week."
