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.

Yeah Jessica's got a great ass now, but look at the tailbags on her mom.

sibling foreplay 

When two people act as familiar as siblings and yet the sexual tension is clearly palpable.

Quit with the ol slap and tickle this sibling foreplay is just about intolerable.
