Frum

This not only includes the careful study of Torah, daily prayers, observing Shabbat and kashrut, and performing deeds of loving-kindness, but also many more customs and khumrot (prohibitions or obligations in Jewish life that exceed the requirements of Halakha).

[5] Frummer can also have a negative connotation, similar to chasid shoteh ('pious idiot'), which is how the Talmud (Sotah 21B) describes a man who sees a woman drowning but refuses to save her, saying: "It is not proper to look at her, and rescue her."

A frummer in that sense is a person displaying a disproportionate emphasis on technical aspects of religion of one's daily life in a manner which actually violates the halakha in a specific case.

[11][12][13] This contrasts with a baal teshuva (BT), which literally means 'master of return' and refers to a Jew who has become frum after a period or lifetime of following a non-Orthodox lifestyle.

[16] Frumba classes are offered exclusively to women who observe frum forms of tzniut modesty laws, featuring music with less explicit lyrics.

[17] Frum Jews are expected to dress in gender-specific, modest, low-cut clothing adherent to standards outlined by Jewish religious law.
