ultrasound blindness

Usually afflicting fathers-to-be and men and women who haven't been through pregnancy yet, this is a visual/brain problem that prevents a person from seeing in an ultrasound image where the baby is when it's perfectly obvious to the doctor and pregnant mother-to-be. Sometimes, but always, the pregnant woman will suffer from this affliction as well. You should worry if the doctor has it too.
Doctor: "Aaand there's our little guy!"
Mom: "Awww, he looks so cute! Doesn't he look beautiful, hon?"
Dad: "I-I guess so... Where is he again?"
Doctor: See? That's his hand with his 4 little fingers and thumb and you can also see his fingernails. And if you squint real hard you can see the individual atoms making up his penis."
Mom: "See honey? See his little peenee?"
Dad: "What...? I- don't... Wha...?"
Doctor to Mom: "He must be suffering from ultrasound blindness. Perfectly normal for fathers-to-be and village idiots. He's just not as awesome as you and I."
*both doctor and mom then laugh at dad's expense*

Word of the Day on October 4, 2026
British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
