Considered to go hand-in-hand with being pansexual, being omnisexual is a bit different. Pansexuals don't tend to view gender in the same ways that we do, whereas omnisexuals view gender normally, they just don't care.

Omnisexuals are attracted equally to all human beings (men, women, transexuals, etc.) They tend to go through phases of gender attraction that switch frequently and will eventually settle down with whoever wins their heart, regardless of said person's gender.

Omnisexual often can be interchanged with the term Pansexual, though there are those who will argue the two are different. Omnisexuals are people who feel attraction towards people of any gender and orientation, including male, female, genderqueer, transvestites, bisexuals, straight, gay, lesbian, asexual, and so on. Omnisexuals see people for their personalities rather than their genitals or gender identity. Omnisexual is not a cover term used for people who will date transsexuals. Bisexual, Gay, Straight, and Lesbian SHOULD cover these terms. A well known phrase of the Omnisexual/Pansexual community is "Hearts Not Parts".
A famous example of an Omnisexual is Captain Jack Harkness from Doctor Who or Torchwood. If it has a pulse, he'll flirt with it. If it doesn't... He'll probably do it anyways.

5.
A person who is omnisexual.
Basically, it's a broad term used to refer to any and all sexual orientations, expressions, and so forth. From homosexuals, to transgenders, to sometimes people with foot fetishes, someone who is omnisexual will love you for who you are.
(Based off my own definition of the term)
