"He is looser crowd mthfck"

1. The word "looser" should be "loser"

2. If you are refering to King Birendra then "He is" should be "He was a loser" else "He is" should be "He is a"

3. The word "crowd" does not make sense in this sentence, and I don't want to edit the sentence on my assumption that the word should have been "coward" as well. If you are trying to say coward you should edit the sentence and say "He was a loser AND A coward mthfcker"
