This is a alternate name for a very simple sexual action where the male picks the girl up upside-down and eats her vagina out as she sucks his penis. This is known as standing 69 because the two humans make a similar stance as a 6 and 9. There is a famous rapper known as Tekashi 6ix9ine so you replace the 69 with Tekashi.
