A person who only posts perfect pictures of themselves online so everyone thinks they're a hot mess, but when you actually meet them, they look like they got hit by a trash truck.
My ex posted a photo of herself in a bikini that looked like it was taken in a photo studio. When I saw her in real life, she looked like she had just been dragged through a mud puddle.
He only posts selfies where he's wearing sunglasses and looking cool. When I saw him at the party, he was wearing a shirt that said 'I survived the 80s' and looked like he had a hangover from hell.
She posted a picture of herself in a dress that looked like it was from a fashion show. When I met her, she was wearing pajamas and had a chip on her shoulder the size of a brick.
