You had better do some more reading. This should help:
A Roman boy's rite of passage, a ceremony or ritual marking a transitional period in life from childhood to adulthood, was the assuming of the toga virilis, the adult toga. The ceremony usually took...

Here are some pertinent excerpts from the article:
The Apostle Paul was a Roman citizen (Acts 22:25-29), and he was very familiar with the Roman customs of his day. In Paul's day, "adoption" was a coming-of-age ceremony, and this is recognizable if we simply look to the meaning of the word "adoption" in the underlying Greek of the New Testament. The underlying Greek word that is translated into English as "adoption" is "
huiothesia,"
G5206 - υἱοθεσία huiŏthĕsia, hwee-oth-es-ee'-ah; from a presumed compound of and a derivative of ; the placing as a son, i.e. adoption (figuratively, Christian sonship in respect to God):—adoption (of children, of sons).

and that word is a compound of two other Greek words, "
huios,"
G5207 - υἱός huiŏs, hwee-os'; apparently a primary word; a "son" (sometimes of animals), used very widely of immediate, remote or figuratively, kinship:—child, foal, son.

which means "son," and "
tithēmi,"
G5087 - τίθημι títhēmi, tith'-ay-mee; a prolonged form of a primary θέω théō theh'-o (which is used only as alternate in certain tenses); to place (in the widest application, literally and figuratively; properly, in a passive or horizontal posture, and thus different...

which means "to place." Therefore, the word "adoption" in Paul's day literally meant "to place as a son," and the context in which Paul used this word tells us exactly what he meant.
As I showed in the excerpts from the article that I linked to, in Paul's day, a Roman boy was under a pedagogue or schoolmaster until the time of his coming-of-age ceremony. His father determined exactly when that time was, and during his "adoption" ceremony, he donned a "toga virilis" or a "toga of manhood" as he was now deemed to be an adult son in society. This coming-of-age ceremony is exactly was Paul was referring to in his epistle to the Galatians. There, we read:
"Now I say, That the heir, as long as he is a child, differeth nothing from a servant, though he be lord of all; But is under tutors and governors until the time appointed of the father. Even so we, when we were children, were in bondage under the elements of the world: But when the fulness of the time was come, God sent forth his Son, made of a woman, made under the law, To redeem them that were under the law, that we might receive the adoption of sons. And because ye are sons, God hath sent forth the Spirit of his Son into your hearts, crying, Abba, Father. Wherefore thou art no more a servant, but a son; and if a son, then an heir of God through Christ." (Gal. 4:1-7)
In the same manner that a Roman boy was under a pedagogue or schoolmaster until the time of his father's choosing when he received the classification as a adult son, we were once under the schoolmaster of "the law" (Gal. 3:24-25) until the time came that God the Father sent forth his Son to redeem us that we might receive the status of adult sons ourselves in God's eyes.
^^^THIS^^^ is what Paul was talking about, and not our modern-day understanding of the word "adoption." In Paul's day, this coming-of-age ceremony was marked by a boy putting on his "toga virilis." For Christians, this coming-of-age ceremony is marked by us "putting on Christ" (Gal. 3:27).
Who has ears to hear, let them hear.
P.S.
This biblical and historical truth is what you previously called my "hokey definition" in your ignorance. I would repent before God for that if I were you.
