We've heard of bumfights - the American video series showing real footage of street people beating each other up.
But now proud British underclass mammas have shown how to do decent fighting videos.
The boy, aged two, is seen crying after being punched in the face by the three-year-old girl and is told by one of the four women in the room "not to be a wimp or a faggot" and to hit her back. The four women, all from the same family, are heard laughing as the toddlers are urged to keep on fighting.
When the boy tries to get away and climb into an armchair, the women shout at the girl to punch him again. She does and the boy is urged to fight back, but says: "No, I don't want to."
The girl leaves the room, and when she comes back the two are taunted and told to fight again.
The court heard that when interviewed by police, one of the women said: "I didn't see any harm in toughening them up. I done the same with my own children."
They're from Plymouth - home of extreme entertainment fighting video.
