“cis” and “trans” are prefixes denoting on what “side” something is. “cis” means “on this/our side”, while “trans” refers to “the other side”, for example:
- “Cisalpina” is how the Romans referred to their side of the Alps (modern day Italy), while “Transalpina” referred to land on the other side of the alps.
- There exist certain pairs of molecules with either a “cis” or “trans” prefix, depending on whether certain identical groups are on the same side or on opposite sides, respectively.
The modern use of “cis” and “trans” is generally about gender. A cisgender person is someone whose gender identity aligns with their sex assigned at birth, while a transgender person is someone for whom that doesn’t hold true.
In this meme, the person on the right is wearing a transgender flag for a shirt, and presumably offending the cisgender person on the left by calling them cis. The meme is making fun of the fact that some cisgender people consider “cis” an insult, when it really only is a neutral and non-offensive description.
Not to be an unfunny nit picker (I don’t know why I’m denying this, that kinda the whole point), but all iphones do have lossless audio streaming via AirPlay. I’m assuming that you specifically meant Bluetooth streaming, but then you should’ve said so. Furthermore, normal aptx isn’t high resolution, only aptx HD and aptx adaptive are. The phone does support aptx HD as well, but once again, you could’ve said so from the start (though 3 characters more or less might make a significant difference to most memes, this one certainly wouldn’t have had that problem)
