This is just to put things into perspective.
At the onset, I know that the word "makababae" exists, but it is a verb. However, my understanding of the original question was about using the word in the same way as "makatao" is used. So, I said that I have not heard it used that way, but just the same, it would make sense if the intention is to mean a feminist or an adjective like "pro-women". I did not bring up the explanation of the verb "makababae" since I thought it would be irrelevant to the question and would have very limited practical use anyway.
The verb is used with reference to the gender of a child expected to be born. The expecting parents, who have only had male progenies earlier, might say something like, "Sana makababae naman kami/tayo sa susunod (Hopefully, we'd have a daughter next time)". So, "makababae" is used to wishfully mean "to give birth to a female child". Since being female or feminine is only possible by birth, I later said that to use "makababae" to mean to become feminine or effeminate, as was done in TikTok, is non-standard since that is no longer possible beyond birth.
There is a Filipino word for "feminine". It is "pambabae". "Mga damit na pambabae" = Clothes for women = Feminine attires.
There is also a Filipino term for "effeminate" "malababae" or "parang babae". "Malababae/Parang babae kung kumilos si Jack. = Jack behaves effeminately.
Hence, when PinoyTaj said that "makababae" means "feminine", I knew that he got it wrong. However, based on my past encounters with him, I also know that he resents being corrected despite the fact that he is not a native speaker of Tagalog. So, I tried to let him see for himself what the problem was with his conclusion by making him think in terms of parts of speech, and should that fail, by asking him to translate the sentences into English. Had he done so, and I believe that he did, he would have realized that he could not translate the sentences into English had he simply used "feminine" as the translation of "makababae". Unfortunately, his reaction was again to instead boldly insist on his being correct and me being in the wrong, and this time by using, of all available sources of correct information about the meaning of Tagalog words, Tiktok.
And the rest is history.
