brown balloon knot 

Brown Balloon Knot is a phrase used to describe the look of the anus.
Next time you have hold of a blown up balloon, take a look at the ring above where the knot is formed. It looks like an arse hole. The brownness obviously comes from the colour of shit.

I finally stuck it in my girlfriend's brown balloon knot last night.

Hollywood Balloon Knot

When someone, probably in the porn business, gets their butthole botoxed so it's silky smooth and wrinkle free.

I bought 5 new pornos yesterday and in all 5 the girls obviously had a Hollywood balloon knot. Even one of the dudes had one.
