Ok I’m a geologist and here’s the thing. Proud isn’t explicitly a geology term (as far as I’m aware) but describing a rock outcrop’s “proudness” is essentially describing its prominence or how much it sticks up above the surrounding topography. It’s more of a qualitative description than quantitative, though you can add a measurement to it. 

Sandstone, being a sedimentary rock made out of, well, sand, can be a fickle rock type. Sometimes it erodes very very easily and other times its surprisingly erosion resistant. For example, Arches National Park in Utah is predominantly, if entirely, made out of sandstone and has these crazy fins and arches sticking out of the ground that you could definitely describe as ‘proud’ I.e. high prominence 

On the other hand, and this is something I’m going to articulate to non geologists because it’s based entirely on vibes but it’s something other rock people can hopefully back me up on, sandstone is definitely proud as a rock type. It’s everywhere. Everyone knows it. It’s fucking sandstone. Well known, well “respected” (not by me though since I’m a dirty igneous fanboy. I simp for basalt). It creates stunning geological formations. It sometimes holds fossils. It can hold water in its pore space sometimes. It records past landforms and clues about the environments that created it millions of years ago. 

Point being, It has such a fucking ego and is so full of itself. It’s like the wealthy frat boy of the geological world. It’s definitely proud and wants you to know how great it is. It’s dad got it a cushy finance job after graduation. 

I don’t much care for it.
