`[真]{ま}[逆]{ぎゃく}` (not `[真]{ま}[逆]{さか}`, which is an interjection standardly
used) is another 若者言葉, or an expression that is used mainly by young
generation (with low education level) that makes me feel uncomfortable.

`逆` is a polarity notion; Something can be either the original (`元`), or the
opposite (`逆`). There is no intermediate values like "half-way opposite",
hence no room for quantitative/qualitative notions like genuine (`真`) or
fake/quasi (`偽`) to come into play. I have no idea what meaning `真` is adding
to `逆`. How is `真逆` different from `逆`? How would you justify the addition of
`真` to `逆`?

Meaning of 真逆, how it is different from 逆
`真逆` seems very similar to the expression "total opposite" in English.

I think we can take `真` here to be an intensifier/emphasis rather than
something that affects the meaning. It emphasizes that something is not just
`少し違う`, but in fact `逆`.

I'd even say that not even `真逆` requires you to be absolutely precise. Let's
say someone wanted to head east (0°). West (180°) would be `逆`. If you saw
them going in essentially entirely the wrong direction -- almost due west --
you might want to use `真逆` to emphasize how badly they're going wrong, **even
if** their true course isn't **exactly** 180°.

It's an abuse of terminology, technically, but I think this is how the
language is used.
