Meaning

A blunt directive meaning 'lurk for six months before posting' — a message board culture rule for newcomers.

半年ROMれ is one of the most iconic phrases in Japanese internet culture. ROM stands for 'Read Only Member,' and the phrase instructs newcomers to spend six months reading without posting so they learn the board's culture, rules, and etiquette before participating. It is used to call out users who post without understanding the community norms. While it sounds harsh, it reflects a real internet philosophy: observation before participation. Still used metaphorically for any situation where someone acts without understanding context.

Examples

1. 空気読めないなら半年ROMれ。 If you can't read the room, lurk for six months.
2. 半年ROMれって言われて悔しかった。 Getting told to lurk for six months was frustrating.
