Incest means having sex with someone from your family. This was a common thing back in the days but is not considered normal any longer unless you live in Alabama where it's still considered perfectly normal to fuck and marry your cousin.
Alabama person: so this is my wife Karen
Normal person: Ohh I thought Karen was your sister
Alabama person: Yeah she is my sister, but she is also my wife
Normal person: But that's incest
Alabama person: I really don't see the problem

Alabama person: Yeah she is my sister, but she is also my wife
Normal person: But that's incest

The act of engaging in sexual activity with an immediate family member acquired through marriage, i.e., step-brother, step-mother, etc. Not to be confused with incest, which would be performed with a blood relative and includes family members outside of siblings, parents, and children (e.g., uncles, close cousins). A prominent theme in the adult entertainment industry, it is markedly less prevalent in the real world. Step-incest is typically frowned upon in polite society, although cases do exist wherein couples can be "grandfathered out," so to speak, if they were doin' the deed before their parents got together.
- I'm so tired of watching step-incest, bro. Don't you have any videos of midgets, or something with circus animals? Maybe both?
- Well, in this one the chick's step-dad IS a midget.. And I've got "My Step-brother Tames Lions, But Can He Tame This Pussy?"

You forgot the incest, shitstain! It's the most important part! Sex is only good if it's your sister kind of!
Hym "Yeah it's like a cannibal suffering cult that is, like, super stoked about how they murdered an innocent guy without remorse... But it ALSO... Has INCEST! It's the most important part! The incest IS the religion! The whole goal of the religious is to perform that sweet, sweet incest ritual! And it's super important to them that people are forced to do it! They really want you to make a chick your sister (technically) and then fuck a baby into your kind-of sister. They're also the gimps for the Jews! And the jews are functionally equivalent to a Jesus. That's a thing too."

basically when people who were raised as siblings and/or family start a romantic relationship. Ex: Any of the "Kissing Booth" movies.
The relationship between those kids is basically moral incest, they were raised like siblings! Gross..
