This term is commonly used for the Volkswagen community to refer to three specific models on the MK4(99-05) line up.
The 3 is for the 337 model, the 2 is for the 20th anniversary model and the G is for the GLI model. All these models share the same engine and transmission and are commonly set apart from the rest due to their sportier looks.
Dude 1: Would this part fit my car?

Dude 2: Yes, as long as you own a 3/2/G.
