"Sex Idiot" is a term popularized by 30 Rock. It refers to a person with whom one has a purely sexual relationship, but who is otherwise an idiot. Broadly speaking, a sex idiot is someone who is sexy, great in bed, but a total moron. One does not exclusively date a sex idiot.

An idiotsexual is a individual who is sexually and romantically attracted to an idiot for being an idiot. There are two main reasons for idiotsexuality. 1 the individual feels empowered because of a lack of intelligence on the person they want to be with or the person they are currently married/dating. 2 A feeling of wanting to nurture from the individual to the idiot or more fun to say 'dumbass'. Most idiotsexuals are heterosexual

It is said of the situation where a person has the bad luck to make contact with his testicles against an undefined surface or object, intentioned or not.
