"Soave Bolla" is a term usually used to refer to an understated table wine* from the northeast ("Bolla"**) section of Italy. However, "Soave Bolla" can also be used as a slightly sardonic descriptor to refer to someone who is attempting to appear suave. (The term can also be used to refer teasingly to someone who is successfully being suave, because, well, come on. Who doesn't want to tease someone who is successful at being suave?)
Variants: "soave fucking bolla," "fucking soave bolla," "hey, you ball a bolla, you think you're soave?", etc.
* It is characterized as having a "restrained, reluctant nose of lemon with some herbaceous notes." I should probably note that this particular wine connoisseur is placing the wine in the context of "The Sopranos" (hit HBO show). Tony Soprano is, in my book, most def "soave bolla," even to the point of being reluctant, on a number of fronts (that of suaveness not excepted).
** The Bolla folks note that "Bolla wines are authentic Italian wines that express the true Italian passion for life."
