The National Cohesion and Integration Commission has released a list of Swahili, English and vernacular phrases which it says amount to hate speech.
The commission says the popular phrase 'sipangwingwi' is among the phrases that contain coded hate speech.
Others are fumigation, madoadoa, mende, kama mbaya mbaya and operation linda kura.
NCIC chairman Samuel Kobia said the words are now banned in public rallies, social media posts and political talk shows.
“This will go a long way in containing hate speech and ensuring our nation is secure during this electioneering period,” he said.
The strategy comes hot on the heels of a storm over the use of the word 'madoadoa' in rallies.
Slang master Alessandro Olocho Santo better known as Madocho was present during NCIC media briefing.
Slang words madoadoa, kama mbaya mbaya and sipangwingwi have become popular phrases at political rallies in the run-up to the August 9 general election.
The use of the phrase modoadoda (stains) at political rallies has in recent days put a number of politicians in trouble with the commission.
They include ODM leader Raila Odinga and Meru Senator Mithika Linturi.
Sipangwingwi is often used by UDA-allied politicians. The phrase derived from a popular urban lingua, sheng means 'we can't be controlled.'
Kama mbaya mbaya and kama noma noma is popularly used by Mombasa Governor Hassan Joho.
It's an indirect dare to an opponent to start a fight
Other words listed by the commission include kwekwe, uthamaki ni witu, watajua hawajui and kihii (uncircumcised).
Moses Kuria is notorious for using the term kihii.
He previously had a case filed against him by ODM leader Raila Odinga for using the word in his reference.
Raila later withdrew the case and reconciled with the legislator in the spirit of the handshake.
