no incesto

Phrase used after doing something sexual with a parent, sibling, child, grandchild, or any close relative to indicate that the act or comment was not incest.

It's like "no homo" but with family. Making sure that they understand that they are not down to commit the sexual intercourse with them. And kindly letting them know they are not about the incest life.

A mythical creature who roams the streets of Philadelphia and persuades homeless junkies to sell their souls for pocket change under a legally binding contract. The Great Incesto is also rumored to have magically flown these "homeless junkies" into the sky and given them the ass raping of their life. It is also believed that The Great Incesto is the mother and brother of all homeless junkies, hence the name "Incesto". Contrary to textbooks and popular belief, The Great Incesto never carries his sodomy in a magic bag.
