A halo Gangster plays is a person who plays halo almost 24/7 and that will do almost anything to win involing agressive smack talk using racial slurs and other things against your mom and if this person loses he wil blame his teamates for being fail people and telling them to go kill themselves. But yet you might want this person on your team beacuse they are usual good

this can also be applied to COD
