Would this be incest??

[Anonymous]

My nephew and my second cousin, so his third cousin. I think it's weird but they talk to each other in a flirty way. They didn't grow up together and our families don't even hang out or anything.

Nope, I wouldn't consider that incest and neither do the states.

Blood. She's my mothers sisters(aunt) granddaughter

Just reread the question. Yes their mothers are first cousins.

Quoting Liz_Rocket:

Is the third cousin related to your nephew by blood or by marriage?

nope, i dont judge

A second cousin is your parent's cousin. Now if it is a cousin's child then that is a first cousin twice removed to you and a first cousin three times removed from your nephew in which case technically it is fine especially as they didn't grow up together. A third cousin is actually your grandparent's cousin.

Quoting Anonymous:

Ok. I got it now. It's not incestous in the legal sense, but I'd find it too close for comfort. I just imagined in my head my own nephew flirting with my cousin's daughter and got the heebie jeebies.

No not incestuous. Incestuous generally implies a power relationship but not always. Kissing cousins, outside of American norms but nothing wrong with it. The could marry and have ten babies and it would be fine.

I wouldn't do it but I'm sure its done all the time! I just couldn't though...some how being in the same gene pool what so ever would freak me the hell out.

Actually, in some states, it is legal to marry your first cousin, under certain conditions.
