NO NO NOOOO AAaAaAaAAAAARGH
I first came across this scream when I viewed Timesplitters 2 (when players get set on fire), and while it's nowhere near as popular as the tediously overused Wilhelm scream (or female/reverse variants), I have occasionally come across it since.
Just that I can remember, it's in No Vaseline by Ice Cube.(first at 0:40)
and in this ad for detergent(at 0:30)
I've tried googling this but have never gotten anything back apart from the Wilhelm scream.
Any sound/movie buffs know the origin?
