Cishet

Cishet, Cishetallo, Pericishet, Periallocishet, Monocishet, Monoallocishet, Perimonocishet, or Perimonoallocishet is a term used by LGBTQ+ people to easily describe people who are not members of the community in any way, shape or form. This means people who are simultaneously cisgender, heterosexual, heteroromantic, suptilic allosexual, suptilic alloromantic, monogamous, dyadic, perioriented, exclusively one of the two binary genders, and afficgender. The term originated within the trans community, particularly among straight trans people, and was created as a way to specify something who is not part of the LGBTQ+ community by virtue of orientation or gender.

Exclusionists
Exclusionists have often used the term cishet to try to erase a-spec people (particularly heteroromantic asexuals and aromantic heterosexuals) from the community as they use the term to imply that a-specs aren't inherently LGBT+ by being a-spec. These people will sometimes use "cishet" as a code word for asexual heteroromantics and/or aromantic heterosexual (and sometimes a-spec people in general).

They will also sometimes use it and similar terms to try to erase varioriented, intersex, polyamorous, non-suptilic allospec, cis nonbinary, and detragender people.

Variants
The term "cishetallo" or "cisallohet" or "allocishet" is sometimes preferable to make it clear that one is not referring to a-specs.

Some use the term "pericishet" (perisex cishet), "periallocishet", or "dycishet" (dyadic cishet) to refer to cishet people who are also perisex/dyadic (not intersex), to show that intersex people have a place in the LGBTQ+ community by virtue of being intersex, even without orientation or gender.

Those who consider polyamorous individuals to be inherently LGBTQ+ may use the term monocishet, perimonocishet, monoallocishet, or perimonoallocishet. The 'mono' stands for monoamorous or monogamous.
