materno-incestuant

Also non-hyphenated, maternoincestuant.

A person who engages in incestuous relations with his own mother. Sometimes referred to as a motherfucker.

The term may have use as in insult.

Tom's not very smart. If we call him a materno-incestuant, he probably wouldn't know what it means.

economic incest

Screwing a family member on a business transaction.

He paid his sister so much below market value for that property that it was economic incest.

ur ancestors incestors

This is the by far WORST insult that can ever be used. Nothing will ever be able to top this insult, as soon as it is said life as we know it will cease to exist.

Johnny- "ur mom gay"
Fred-"ur dad lesbian"
Johnny-"ur sister a mister"
Fred"ur bro homo"
Johnny-"ur granny tranny"
Fred-"That;s it, ur ancestors incestors"

The universe implodes as everything that exist is destroyed. All you can hear is the screams of every single person being tortured in hell as everything comes to an end with one final explosion.

incest

The way the British royal family keeps itself German.

It is illegal for any member of the British family to marry anyone who isn't a blood relative. (Thanks to the 'Royal marriage act' of 1716) Even lady diana was a distant cousin.
