Named for a dudes penis

Another one u reminded me of that mom used when I was a teen and I hated it was red rocket

Oh that’s very cringe!

Something my aunt used to say that I thought sounded weird / cringey was ‘crown jewels’

That and “family Jewels” nice addition

Where I grew up, a "red rocket" was an animal's penis -- usually a dog's. I think the only time I heard it applied to a human penis was explicitly in the context of having sex "doggy style", in keeping with the animalistic context.

That and “family Jewels”

In my world the "family jewels" were very specifically the testicles. After all, they were in a pouch to protect them and you need them to have a family which made them very precious!

I don't know that I'd use "cringe" but I do know whenever someone mentioned 'family jewels' it used to make me feel funny "down there", I guess because of the way it implied there was something of great value in my briefs I needed to keep safe.

I just remembered two others not sure if they were listed yet

The one eyed monster

The snake. It was part of a game/phrase wakey wakey hands of snakey

[Robert Brooks]

Yes, same actually, now I think about it ‘crown jewels’ / ‘family jewels’ definitely implied testicles as well / instead.

A blend of your two, Lostboy: at school I remember hearing ‘one eyed trouser snake’
