From the Friends TV show:
Monica: I have some pretty exciting news.
Phoebe: You're pregnant!
Monica was in a relationship and had expressed that she wanted kids, but didn't have a tummy and hadn't given any hint whatsoever that she may be pregnant.
Is there a word to describe these guesses that may be technically feasible but that are very exaggerated?
It's somewhat like the domino effect meme
For example:
- You posted a picture of a house. Did you buy it?!
- Well that's a ____. No, I didn't, I just like taking pictures.
