Chants of "let's rape her" directed at a woman on a DART train have been described as 'disgusting' and 'distressing'.
Gardaí have launched an investigation into the incident, which happened as the woman got off a Malahide-bound train on Wednesday night.
Dublin Fingal TD Alan Farrell says this type of behaviour is all too common.
"A group of young men targeted a young woman and roared horrific chants after her.
"What these young lads were shouting was shocking and distressing, and showed their complete lack of respect or regard for women.
"This story, unfortunately, will not come as a surprise to most women as these scenes occur all too often.
"Women across the country are frequently on the receiving end of misogamy, harassment and intimidation.
"Put simply it has to stop - and yes, the Government, the Gardaí and the courts have a role to play.
"But so do we, particularly men".
"I witnessed an act of misogyny and downright sexual harassment that was driven by the culture of toxic masculinity that exists within our society."

Spokesperson for Irish Rail, Barry Kenny, says no one should have to put up with such disgraceful language.
He says a Garda investigation is underway, and that security teams are on patrol at all times.
"An investigation is underway obviously to assist the Gardaí in identifying those that were involved.
"Nobody on board should have to hear that - and particularly our women who are travelling with us shouldn't have to hear disgusting and disgraceful language like that.
"Between Deputy Farrell's account and CCTV, we're confident we will be able to those that are involved.
"We can divert teams quickly to situations as they arise; thankfully we have seen the incidents of anti-social behaviour reducing".
But Mark Gleeson from Rail Users Ireland believes it is not an isolated incident.
"Over COVID, even though passenger numbers are down massively, the number of reports of anti-social behaviour actually seem to have gone up.
"And that's because [of] quieter trains, fewer people around - the protection of the crowd is gone".
Iarnród Éireann says anti-social behaviour can be reported to its control centre by texting the word 'Train' and the details to 51444.
