Wikipedia states,
The pizza effect is a term used especially in religious studies and sociology for the phenomenon of elements of a nation or people's culture being transformed or at least more fully embraced elsewhere, then re-imported back to their culture of origin,[1] or the way in which a community's self-understanding is influenced by (or imposed by, or imported from) foreign sources.[2] It is named after the idea that modern pizza toppings were developed among Italian immigrants in the United States (rather than in native Italy, where in its simpler form it was originally looked down upon), and was later exported back to Italy to be interpreted as a delicacy in Italian cuisine.[3]
Essentially, an event or trend that has no paritcular significance natively but when adopted by a different culture or place, become cool and more popular in the place where it was already present originally.
Cool!
