A flat-chested girl who intentionally makes her boobs look big on social media and/or dating sites. When they are finally seen naked in person, it is learned you've been completely duped by her lie.
Person 1: "Dude, how was your date with Melissa and her huge tits?"
Person 2: "Bro, they aren't huge; she wears padded bras. She's an A-Cup...she's just another C-Cup Catfish."

That kind of Batman's trap that lead you to something unexpectedly different from your initial expectation, e.g. ending up watching age-inappropriate animated movie titled "Sausage Party" (2016) when you akcually expect to watch kid-friendly animated movies
I thought I was in for a fun family movie night, but catfishing hit hard when I ended up watching the wildly inappropriate 'Sausage Party' instead of a kid-friendly flick!
