Tailbag

A droopy ass of some fat old broad who is waddling in front of you at the local Walmart. You know that thing hasn't had a good wipe between those floppy cheeks, the matted fur aound that cavernous hole must have an odor emenating from it like the stench of a thousand corpses. Thankfully those floppy tailbags hold that stench in securely unless one of them suddenly flops to the left or right. You'd better get around her quick just in case.
