I think this word means: Someone who “lives on the edge” or pushes the limits of things.

Actual definition: \boo-luh-var-DYAY; bul-uh-, noun:

1. A frequenter of city boulevards, especially in Paris.
2. A sophisticated, worldly, and socially active man; a man who frequents fashionable places; a man-about-town.

Remark: Awesome.
