The shadow home secretary launched the four-letter tirade in a Parliamentary bar after Ms Abbott helped vote through the Article 50 bill.
Mr Davis, MP for Haltemprice and Howden, is said to have moved to kiss Ms Abbott at the Strangers' Bar in Westminster before walking away laughing.
The bizarre incident was reported on Twitter by Paul Waugh, the Huffington Post's political editor.
He wrote: "Vignette from Commons' Strangers Bar: David Davis moves in to give Abbott a kiss. She recoils and tells him to f*** off. He walked away laughing."
When contacted by Express.co.uk, Ms Abbott's office said they were aware of the reports but had no further statement to make.

Speaking after Wednesday night's vote, Ms Abbott risked angering Labour voters after she criticised the type of Brexit people had voted for.
“I respect the result of the referendum and no one wanted to thwart it, in a perverse kind of way,” she told Newsnight.
“But we need to be clear, this isn’t Tony Benn Brexit: this is Donald Trump Brexit – and its got a very ugly side.”
The comments from the shadow home secretary illustrates the divide between much of the party leadership and traditional Labour voters who were instrumental in winning the vote to Leave.
Labour leader Jeremy Corbyn imposed a three-line whip on Labour MP’s forcing them to support the government’s Article 50 bill – which passed through the Commons yesterday any amendments.
