A big butt. Really nice, and not fat. Unlike the girl above me who seems to think she is thick and has a nice butt. She's just fat. She has a sloppy ass.
Damn that girl's ass is nice she has a badunkadamn!

Get the badunkadamn mug.
Not just a nice round booty but a nice BIG ol round booty. A booty that would make a grown man cry (especially if you're from the durty souf ).
"Look at that girl, she's got a badunkadamnnn."

(draw out the "damn" if it's an extra lucious booty)
