why groupo??

From Sheldon Brown's glossary:

Gruppo: Italian for "group." The use of the term "gruppo" is sometimes considered an elitist affectation, especially when referring to parts which are not of Italian manufacture.

Grouppo: Common misspelling of "Gruppo."

i still don't get it why people write groupo or grouppo (?) when it comes to mention that, for example, my bike is equipped with full dura-ace "groupo"?? 😕 😕 anyone tell me what's that "groupo" thing different (or it has a special meaning??) to writing the proper english word "group" 😕

You are thinking of "gruppo" which simply means "group" in Italian. Since the Italians figure very prominently in bicycling history, we just honor them by using the word gruppo to mean the complete drive train where each component is the same brand and model. Sometimes, but not always, a gruppo includes the seat post, pedals, hubs, and head set. It just depends upon how far you want to carry it.

Italy thanks you for the great honor. 🙄

We don't mind actually... although we prefer when people spell the word correctly... :p
