When you reuse a condom in an instance of 2 or more sexual partners. The " Sock Hop " or so-ho is most occurring in the fashion of at least one male and two females. A pairing of m/f /f is considered a straight event where no emphasis is put the act between female A and female B. If the condom is used it is not replaced after ejaculation or removed. with use in following partners ejaculation may occur again and again. This is said to provide more lubrication. A "Sock Hop" can only occur in one session or sexual acting's once the original grouping is dissolved the "Sock Hop" may cease. THIS IS NOT CONSIDERED A NATURAL SEX ACT OR ONE I ADVISED BY ANY SEXUAL EXPERT.
