What was the obscure ref in question?

I was listening to some streams last night. One of the guys said "did ye better" really quickly, and his teammate said "like super paper mario?" Needless to say, absolutely nobody got the ref and I was assaulted with war flashbacks

Nobody got a reference to Super Paper Mario? Wow, I thought everybody knew about it, seeing as it was an entry in a hugely popular franchise on a hugely popular platform.
