Brothering

[Kit]

Similar to parenting, where parents [carry out] their duties as parents, this is where brothers carry out their brotherly duties.
The type of [brothering] depends on age: if you are an older brother, your duty is generally to [embarass] your sibling; if you are a younger brother, your duties tend to be to annoy your sibling and follow them around.

[Britney]

The action of admitting a tradesman, apprentice, etc., into a brotherhood; a ceremony marking this; now historical.
