Liam Millar attacked one partner when she was pregnant, warning he would "stab the life out of you".
The control freak assaulted another woman on several occasions and accused her of sleeping with her own father and sneaking out at night to meet men.
Millar (22) admitted a catalogue of domestic abuse charges against three women at Hamilton Sheriff Court on Friday.
Jennifer McCabe, prosecuting, told the court: "When police charged him he said it was 'lassies being lassies'.
"He did not seem to care about his actions and boasted that women 'just want all the f...... money' despite the fact that he was unemployed.
"He belittled the charges and laughed as he was told about them."
Millar, who will be supervised for a year on his release, was also handed non-harassment orders preventing contact with his three victims for five years.
Millar assaulted the women at addresses in Motherwell and Hamilton during 2019 and 2020.
Sylvia Lyttle was three months pregnant with Millar's child when he grabbed her by the throat and pinned her against a wall, lifting her feet off the floor.
The attack happened at a flat in Grange Tower, Motherwell, on October 20 last year.
Ms McCabe stated: "Seconds before she would have blacked out, he released her.
"He screamed in her face and punched her twice.
"He then grabbed her by the throat so tightly she could no longer scream. She feared for her life and the safety of a child who was in another room.
"Millar punched her on the face to stop her screaming. He grabbed her by the hair and pulled her to the floor.
"She curled into a ball, trying to protect her unborn child. The accused left and drove away.
"She was taken to hospital to be checked over. Fortunately, a scan showed there were no issues with her baby.
"Over the next few days she got messages from the accused who said he was looking forward to killing her.
"One stated 'I can't wait to stab the life out of you. I'll kill you this time, Sylvia'."
The court heard that Millar subjected a previous partner, Emily Hobson, to repeated physical abuse in Hamilton.
She suffered "numerous" injuries at his hands and on one occasion needed stitches in a burst lip.
But the fiscal said she was reluctant to report Millar as she was "fearful of the repercussions" and he had "control of her".
Millar pursued her in his car one day and deliberately crashed into the back of her vehicle.
Apart from the violence, Millar subjected Ms Hobson to vile verbal abuse.
Ms McCabe told the court: "This included accusing her of sleeping with her own father.
"He caused her extreme fear and alarm by saying he would kill her.
"On one occasion he accused her of sneaking out during the night to sleep with people. He then started to choke her."
Millar admitted assaulting a third partner, Bryony Boyd, at an address in Gorely Place, Motherwell, on Boxing Day 2019.
He jumped on top of her after a row over a bank card and punched her on the face.
