A friend who is your ex (which you might also have sex with)

This category of relationship is an advanced stage which may exhibit qualities of best friends, arguing like siblings or an old married couple, irrational jealousy, unspoken understanding of each other in social gatherings, and/or having amazing sex, likely in the form of a booty call (because bad sex probably wasn't the reason you broke up in the first place)

"Well we are friexes, you know how it is, bickering, doing it, having inside jokes, and purposely avoiding certain conversation topics...it's alright..."
