What is Belly Bangers?
1.
The act of not finding the hole on a fat chick and picking a roll to bang instead.
Slick Willy couldn't find her puss so he belly banged her.
2.
The act of attempting coitus with a sexual partner's belly-button. Works better with innies than outies.
She didn't want me to slip it to her quite yet, so I gave her a few belly bangers to remember me by.
