LGBTQIAPK is one of several acronyms intended to represent all current varieties of sexual perversion. This acronym stands for: Lesbian, Gay, Bisexual, Transgender, Queer (or Questioning), Intersex, Asexual (or Aromantic or Ally), Polyamorous (or pansexual) and Kink. There seems to be some minor disagreement over what each letter means, while others just add in multiples of each letter to include them all. Ths means that the acronym can also be: LGBTQQIAAAPPK
Some also say that even this is not a suitably detailed list, because other terms such as Agender, Bigender, Trigender, Pangender, Polygender, Cis, Gender Apathetic, Demigender are not included. To be more "all-inclusive" and avoid causing someone to think someone else might be offended, sometimes a plus sign is added on the end of whatever acronym is used, to represent those not listed.
