relationship which involves four persons. This can be
romantic, sexually, intimately, or platonic, but lasts for a
long time. They keep the love and sex between themselves, they do not date other persons.

- No, Andy and Will are a
gay couple, and Burt and Greg are a gay couple, but they spend all their time together, day and night. They all love each other and
have sex together.
- Oh, so no foursome, but
a couple of four people.
- Yes, a quadrouple.
