badunkabump 

The distinctive shape of a pregnant momma that is defined by her baby bump and badunkadunk in unison.

I just shared a hawt picture of my wifes badunkabump on the interwebz.

Her badunkabump is so pronounced, it's faptastic!

Badonkadump 

One of those shits that feel as if your growing a second asshole. Your body stiffens as you go through this shit process. After the aching pain, a little sting may occur around the opening of the hole because of the excess stretching it has gone through. After the whole process you feel very light on your feet usually.
This does not happen frequently (well it shouldn't).

Person 1: Yo, I took the most manliest shit the other day; it felt like I was literally having a truck come out of my asshole!

Person 2: Ugh... a badonkadump. I hate having those because they hurt so damn much.

A huge dump.

Yo, Jovanny, I just took a badunkadump that clogged up your toilet.
