You may be related to your second cousin's cousin, or you may not. It depends on the specifics of how the two cousins are related.

Any of their great grandchildren are your second cousin's second cousins or first cousins - and they are not related to you at all.
You and your second cousin's children are second cousins, once removed. Your children and your second cousin's children are third cousins.
The first cousin of your dad's first cousin is also your your dad's first cousin or is not related to him or to you. The children of two first cousins are second cousins to each other. So the son of the first cousin of your dad's first cousin is either your second cousin, or is not related to you at all.
