His issue was phrasing. The woman used a euphemism which significantly shifted her perceived intentions. “Look at his little wee-wee” is far removed from “look at his little penis.” Synonyms are not created equal, so simply substituting without considering connotation will only cause confusion. He should have said “get an eyeful of her little vagina.”

I think if he referred to it as her little pussy or cunny it would make it significantly worse.

That’s more adult slang for vagina. Little kid euphemism would be something like hooha or twinkle.

Are there people seriously calling vagoos as hoohas

You call called them vagoos. I’m not sure you have much room to judge.

Makes them sound less pointy

Why do you think of vulvas as pointy?

The characters sound. I don’t know what you mean

I don’t think I particularly want a pointy sounding word for vulva because I don’t think of vulvas as pointy. I was just curious why you want a pointy word rather than a round one.
