Ruling party's MP Zunaid Ahmed Palak made the demand on Monday to which Prime Minister Sheikh Hasina and other lawmakers thumped the desk in approval.
The suggestion comes at a time when the budget session had been rocked by offensive language being used by both the ruling and opposition MPs.
"The image of 350 lawmakers are tarnished due to the obscene, indecent, and unparliamentay language used by several MPs. The Parliament is being dishonoured," he said.
Opposition's Rahana Akter Ranu, Syeda Ashifa Ashrafi Papia, Shammi Akter and ruling party's Nazma Akhter, Apu Ukil and Fajilatun Nessa had rocked the House in recent weeks by frequently using 'unparliamentary words'.
Speaker Shirin Sharmin Chaudhury even cautioned the MPs about the language they use in parliament, but with little impact.
As BNP's Rahana Akter Ranu ignored the warning during Sunday's session, the Speaker turned off her mike six times.
Palak claimed each minute of Parliament’s proceedings cost the people Tk 30,000 and reminded the House had a child gallery too.
"Still, the Parliament is being dishonoured by [offensive] speeches by several lawmakers," the Awami League MP said.
"On Facebook, 3.7 million youths are saying 'We Hate Politics and Politicians' because of these foul-mouthed parliamentarians. They don’t want to see some lawmakers dishonouring 350 MPs," he said.
Palak urged the Speaker to take a 'tough stance' to stop the use of words not suitable for the House.
"Please take tough steps against them (those using offensive words) so that we (the MPs) are not insulted by their speeches.
"Expunging unparliamentary speeches alone won't do. Please fine Tk 30,000 for each such word used," he said.
Opposition MP Shammi Akhter recited a poem in Parliament last week which was expunged.
Palak requested the Speaker to expel an MP for at least one day for indecent remarks.
Both the ruling and opposition lawmakers supported him.
He asked the media not to publish the offensive language used by MPs to discourage them from using such language.
On allegations against him, the lawmaker said he did not make any indecent remark against any of the four national leaders as alleged by Khulna's Nazrul Islam Monju MP.
Bangladesh Jatiya Partye (BJP) chief Andaleeve Rahman Partha, giving a clarification, said his social status, educational qualification, and family heritage did not 'permit' any personal attacks.
Ruling party's Shamsul Hoque Chowdhury MP on Jun 17 had asked Partha to know about his father's income source. The scathing attack came after the opposition lawmaker spoke about LGRD State Minister, the Home Minister, former Communications Minister, and minister without portfolio Suranjit Sengupta while speaking on the government's 'corruption'.
Partha demanded forming a committee to prevent unparliamentary speeches in the House. "There's a gallery for children in Parliament. They are learning from your indecent speeches."
He alleged both the ruling and opposition lawmakers forget all norms once an 'offensive' statement is made on the families of the Prime Minister or the Opposition Leader and tend to go berserk.
Monday's session began at around 10am.
