This is the original video btw, I was on my way back from Strasbourg, France and one man (black) was hitting on a woman and didn't stop when she told him to go away, then he goes back and an elder man (probably 55-60) sticks up for the woman, then they end up arguing verbally for maybe 30 seconds until the black man throws the first punch (im presuming he was drunk based on behaviour and the clear liquid in the coke bottle I thought was vodka) then the elder man comes back until they're both held back, the black man is told to exit the train or the ticket man would call the police so he left while saying in French "nique ta mere, nique ta grandmere, grosse put" which means "fuck your mom, fuck your grandma, big bitch"
