2 sets of couples who are in a romantic relationship together. Beyond just swinging or swapping wives or other ethically non-monogamous relationships 'quople' indicates both partners are interested in relating to both other partners on a mental, emotional and sexual level but together. Quople indicates a certain committment beyond playing and while non-traditional a quople feels very much
like a
man dating a woman only there are
two of everything and everyone is comfortable with it. True partners for life expressing their individual desires and nature as
one but to another couple.
"
Steve,
Marie,
Lynn and Lee, have been together as a quople now for almost a year"
(I prefer Quaple because the prefix qua indicates a foursome more than quo but there is already another (lame) meaning on urban discionary for quaple
