Relaxed "Bridechillas" are becoming the new bane of weddings, as opposed to "Bridezillas."

Bridezilla and Bridechilla have a lot in common: They both want their wedding day to be filled with joy. They also both appear to provide a fair amount of pain and stress to the members of their wedding parties.

Don't know Bridechilla? That may be a good thing, according to an account on Huffington Post by Rachel W. Miller, who wrote about the anything-but-laid-back stress this "chill" gal creates for those around her.

The Urban Dictionary offers this description of the oh-so-cool bride: "A bride that remains calm, cool, and collected during her entire wedding experience. Bridechillas never use phrases such as 'my day, the most important day of my life, don't ruin my day, etc.' A bridechilla is not defined by her wedding …."

But there are frostier descriptions.

Jodi Chick, who served as a recent bridesmaid for a too-relaxed pal, described the dilemma to Miller: "My friend was absolutely 100 percent not the kind of girl who had dreamed of her wedding her whole life, and she found the idea of putting on an event of that size totally overwhelming. Since she had no vision, everything was a possibility, and she had a huge fear of missing out. To her, everything seemed like a good idea. 'Do you want printed invites or handmade?' 'That sounds nice!' 'Do you want bright blue or pastel blue?' 'I like all blues.' 'Which cake flavor do you like?' 'I don't know, which one do you like?' She was so easygoing and eager 'not to be a hassle' that it was actually a nightmare."

A Bridezilla lays out every detail and is demanding in the process, bulldozing through anyone who offers their own opinion. A Bridechilla, on the other hand, has trouble pinning down the details or leaves it to others, who then find themselves with an extra load of work and the responsibility to see that the event goes well.

By the way, 'Chilla and 'Zilla can both trust their bridesmaids with certain decisions, according to Loverly, such as dress, hair and shoes.

"Letting your bridesmaids choose their own dresses means you won't have to find a dress that suits everyone's budget, body, and style," writes Miller. Of hair, she says, "Everyone's hair is different and an updo that looks amazing on one friend can leave another friend looking less than her best in pictures." And on the topic of shoes, she adds, "You may look at a pair of shoes and think 'Oh, perfect!' while your bridesmaids are thinking 'Oy, blisters!’ ”

On the Internet, there's not much documentation that Bridechillas actually exist. But there's a lot of proof of Bridezilla big-footing her way across Wedding Land. Some of it, by the way, seems perhaps a tiny bit … well, fictional.

Business Insider documented 10 close encounters with the specimen, ranging from the charmer who fired her greeter because a tattoo peeped out from her shoe straps to the gal who blocked the door so hungry guests couldn't leave her low-cal festivities.

On the more practical side, for the bride and groom, is a recommendation regarding the size of your wedding: According to a recent article in the Deseret News, research shows that bigger wedding parties are associated with higher-quality, happy marriages.

The study doesn't comment on the bride's demeanor during her big day.
