Usually said when someone goes on a long rant about something you don't care about and fails to bring up a valid point, anything worth merit, or a compelling argument. Also said when someone speaks mindless drivel. Usually will cause a complete dumbass to rage and just give up.
dumbass " Ya man, I'm the greatest person to ever live. Sure I never went to college, made a fortune, helped out the less fortunate, not the best looking person, and have an IQ of 72, which is legally retarded and lower than Forrest Gump's, but I have the coolest wallet ever!!
Me " Your Point?"
Dumbass " Man fuck u man, you're just a hater and you're hating on my swag and success!! Quit being a player hater, even though I get no ass and live with my mom and I'm 40 and still a virgin.
