Nga Nga reapeated provides the sound of an intense, nasty blowjob. This sound is made when the head of the penis reaches the back of your partners throat and engages the "gag" reflex. This sound is made better while the receiving partner humms a tune while doing the business.

Also, emulating this sound in an office setting toward an employee that is a dick sucker provides great humor.
I was giving it to that bitch good the ole Nga Nga! her mascara was running as well.

Do you see that brown noser always sucking up to the boss Nga Nga!
