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!

Nga is a very popular vietnamese name. But it sounds like complete nonsense to someone who does not have a vietnamese accent. Many girls named Nga are quite beautiful but be weary, ask how she pronounces it or she might become offended and curse you in vietnamese.
Nga is a very nice girl. Nga is a complete twat. Nga is very aggressive.
