SLANG : Baby Goggles

A phenomenon where the parents of an ugly baby think their baby is adorable and no one else does.

Nancy: Here's our little bundle of joy! Isn't she just the cutest thing ever?!?
Lisa & Kate (after one look at Nancy's ugly baby): Ohhhh...! Yessss....
Lisa to Kate: I think Nancy has baby goggles - that's got to be the ugliest baby I've ever seen!
