n. An overpriced, trendy bicycle ridden by arrogant, social-climbing, elitist, post-middle age, post-yuppie douches who think paying $8000 for a titanium bike will make them more important and a better athlete. Usually riders of serottas think they're better than everybody and often can't climb a highway overpass. These penis extenders often spend more time on the roof of an Audi SUV than they do on the road.
Every time you see some expensive bike ridden by someone with a paunch, a questionable fitness level, and a garish italian racing kit, it is often a SEROTTA
