Cis means same as opposed to trans which means opposite it’s commonly used to describe the shape of molecules in chemistry but is also used to say if a persons birth sex is the same (cis) or different (trans) then their gender
Het is short for hetero which means different vs homo which means the same so if you had homogenized milk it’s all uniform and the same vs a heterogenous mixture which would have some areas of extra fat. Those are used as hetero and homo sexual where a homosexual likes people of the same sex and heterosexuals like people of the opposite sex
So a cis het male is a dude whose not trans who likes banging chicks

Cis effectively means not-transgender, so born as exacly the same gender you identify as. ‘Het’ then means heterosexual, making cis-het someone who is either completely male and into women or completely female and into men.

I have definitely heard cis in terms of cognition so I don't think its specific to sexuality.

It is a prefix that isn’t specific to gender (I don’t know of a particular use in sexuality though that doesn’t mean there isn’t one), but in other uses that I know of, it isn’t used by itself as a descriptor of an aspect of a person’s identity, but as part of some other word. It basically means the opposite of trans (as a prefix, so not just “cisgender means someone that isn’t transgender”, but anywhere that the prefix trans- could be used, for example, when talking about spacecraft visiting the moon, the space farther away from earth than the moon is is sometimes referred to as translunar space, and conversely, the space between the earth and the moon can be called cislunar space). In general, if one is talking about people, especially if it’s just used by itself with nothing else attached, it just refers to everyone other than transgender people.

Similarly, carbon=carbon double bonds in fatty acids can have the free hydrogens either on the same side or on opposite sides of the double bond, and are known respectively as cis or trans fatty acids.
