to ask what this is?

Insect nest or flower bud or..?

Vote? Sorry.

Ooh I’ve never seen that before 🤔

Looks like it’s on a rose?

Robin's pin cushion. It's a type of gall, which is created by some type of gall wasp. Google diplolepsis rosae.

Look up Robins Pin cushion on RHS website.

Are you on reddit? Post it on www.reddit.com/r/whatsthisplant/ and someone will name it in minutes

Bramble I think. I was out on a walk and I saw 3 or 4 of them.

I see PP already did, too slow. :D

Sport on. Thank you very much. And to everyone else.

I'm glad I didn't prod it too much now!

I suspect if you had prodded it, nothing would have happened anyway, even if it is full of wasp grubs.
