A person (Be they Straight, Gay, Lesbian, or Other) who will sleep with either sex just so they can have a sofa to sleep on (i.e. A roof over their head).
Reason for the definition and term Sofa sexual, Sofasexual is. I observed a guy once who swore up and down he was gay, But a week later I saw him hanging all over a girl (acting all boyfriend girlfriend like with her), just so he could have a sofa to sleep on.
