cousincest 

COUSINCEST = COUSIN + INCEST, ie, when cousins have sex.

"Cousincest" is a misnomer. Cousin sex is NOT incest according to Modern Medical Science (cousins have a 96% chance of producing a normal, healthy child), the Bible, or most marital laws around the world (including Europe, Canada, and much of the USA).

Confusincest 

The strange phenomenon where all of your close friends become an extended family where "blood lines" overlap and make absolutely no sense to the people involved or those observing from a sane vantage point.

Friend 1: I have 3 moms, one of them being male, 4 daughters (1 adopted), my stepmom is also my sister, my other brother is the black sheep literally, another sister is my synchronized sex twin, and one of my daugters has like, 3 dads.

Friend 2: O_O...that's total confusincest...can I join?
