A person that becomes a douchbag whenever there is a pretty girl around. Typically, it is either a girl being ignorant out of jealousy, or a guy being ignorant trying to impress the vagina.
Examples of people being a Vagina Douch: Carl is typically such a nice guy, but he becomes a complete douch whenever Valerie is around. Hey did you ever notice what a douch Tina can be when a hot girl is hanging out with us?

Man, Will showed up unexpectedly at my house on Christmas with present,what a Douchbag Santa!
Someone who is completely oblivious to the fact that traffic is completely stopped on the other end of a large intersection and continues to drive out into said intersection simply because they have a green light.
When the light turns red and the crossing traffic gets a green light, there is now nowhere to go because this moron is blocking traffic, creating a gridlocked situation in extreme cases.
I was 25 minutes late for work today because some gridlock douche turned Route 9 into a parking lot near the mall.
I stopped at the green light because I could clearly see traffic was bumper-to-bumper on the other side. So when the jackass behind me started beeping I yelled back, "Sorry, I'm not a gridlock douche like you."
