Ms Sherriff, the Labour MP for Dewsbury, told the Commons the prime minister had "continually used pejorative language to describe an Act of Parliament passed by this House".
Pointing to a plaque in the chamber, commemorating Mrs Cox, who was murdered by a right-wing extremist, she said: "We should not resort to using offensive, dangerous or inflammatory language for legislation that we do not like, and we stand here under the shield of our departed friend with many of us in this place subject to death threats and abuse every single day."
"They often quote his words 'Surrender Act', 'betrayal', 'traitor' and I for one am sick of it.
"We must moderate our language, and it has to come from the prime minister first."
In response, Mr Johnson said: "I have to say, Mr Speaker, I've never heard such humbug in all my life."
