My mother’s sister’s son is my cousin; let’s call him “John”.
John’s father’s brother’s son — let’s call him Mark — is John’s cousin.
Now, Mark isn’t my direct cousin as we don't share any immediate ancestors. What kind of relationship do I have with Mark? I think this too is some sort of cousin.
I always thought this was second cousin, but it turns out, I have blood relation to a second cousin through great grandparents.

Conclusion: I would call him cousin of cousin.
