What does [Insert family member] twice/three times/four times/etc. removed mean?

[DMeisterJ]

The "removed thing"

If your grandmom/dad has a cousin, they are your first cousin once removed.

If your great grandmom/dad has a cousin, they are your first cousin twice removed

If your great great grandmom/dad has a sister that has a cousin, they are your second cousin, once removed

Or something like that.

Basically, it's cousins of your parents when you add the whole removed thing.
