What is a second cousin three times removed?

A second cousin three times removed is a second cousin from a different generation: your second cousin's great-grandchild, or your great-grandparent's second cousin.

The shared ancestors are great-grandparents to one of you and great-great-great-great-grandparents to the other: 3 generations down on one side, 6 on the other.

Two ways to be one

Your second cousin's great-grandchild is your second cousin three times removed.
Your great-grandparent's second cousin is also your second cousin three times removed.

How to work it out

Find the ancestors you share and count the generations from them down to each of you: 3 and 6.
The smaller number minus one gives the cousin degree: 3 minus 1 is 2, so "second".
The difference between the two numbers is how many times "removed": 6 minus 3 is 3, so "three times removed".
