Because people are visual I'll give a demonstration.
In most situations when you underexpose an image it blows it all the white and you lose details in important places. Things begin to feel cartoony.

Most people including beginnings photographers would shoot looking for the skin tone 18% gray blowing out the whites but leaving rich blacks as sort of a middleground and that typically works in most applications. But for a wedding photo it's actually kind of better to make everyone look dreamy like that.

but notice how now it looks like her best friend took it with her cell phone๐คท๐ฝ 
Like I said. Certain situations. Certain feels.
