A huge bush on a lady friend, as in a vagina jungle.
Wow that chick I fucked last night has a huge vungle
Due to the definitions of both chungle (the crumbs at the bottom of the chip bag) and vungle (hairy vagina), this sentence means to shove the crumbs from a chip bag unto ones vaginal canal.
"Bro I am going to fucking chungle your vungle"
