Facilinatrix
A facilinatrix is a woman who takes care of the messy parts so the main girl can look good. She’s like the backup plan if the main girl gets distracted or needs a hand to keep everything running smoothly.
'She’s the one who keeps me from getting too cocky.'
'She’s like the backup dancer who’s also the DJ.'
'She’s the one who knows when to stop talking and start sucking.'
