6669 

The number associated with Devil Sex. As "666" is the mark of the beast, or Satan, adding a "9" to end of it transforms it into a version of "69," or the number associated with the position of simultaneous oral sex.

This can be used to denote sex that is inherently immoral in nature (such as adultery) or sex that just feels so incredibly glorious, one can only think it must be wrong.

I've fooled around with this guy off and on, even though I know that he's married. We 6669 it.

Inspired by the beautiful relationship shared by Dave Franco and Alison Brie, it's when two consenting adults both start shitting during a 69.

Oh, honey, we need to spice up our love life, let's turn this 69 into a 6669...
