Sign that a Douchmobile is approaching is obnoxious engine revving used to compensate for a small penis.
May be a nice, current year model purchased for the exact purpose of hiding his chode, or may even be a hunk of shit souped up to look high performance;

**Please note, it is common knowledge that drivers of these type of vehicles are most commonly defined under the douche category with applicable similar definitions such as douche nozzle, douche bag or douche knob to name a few. These individuals are typically very easily identified by cocky, irrational and generally childish behavior. Many of these drivers refer to their douchemobile(s) as "american muscle" which is generally a pseudo-patriot excuse to waste more gasoline during the middle of an oil crisis.
