Bestie-5 

An outburst of exuberance during group sex, often prior to the onset of orgasm, during which two of the parties involved in a BFF relationship slap hands above one another's heads in a traditional "high-5" gesture while simultaneously yelling "besties!"

You bestie-5ed with Dave! I thought I was your BFF!
