munga junga 

when a manboob is pulled and snapped back into place it occasionally bounces up and down a total of 2 or more times. much like the milkshake joke

GUY1-"hey look over there"
Guy2-*looks
GUY1- pulls back boob and lets go "munga junga"

jungajunga 

1. To get your freak on with anyone or anything.

2. Genitalia. Oh baby.

3. I am the bomb.

"Yeah, so, my boyfriend came over yesterday and we did a little jungajunga, if you know what I mean"

"Ow, my jungaaaaaa."
