Simple and blatant acronym for "When buttersnaps appear, Peaches no longer Interest me".

I honestly don't know why you had to look that up.
Josh: Hey man, want a bite of this peach? It's delicious! Woah! Look at those buttersnaps that just appeared!

Thomas: Josh, I'm gonna have to pass on that peach... WPI.

Josh: Dang!
