To take a dump. People use the expression grow a tail to say they're taking a dump, and if you know anything about GG Allin then you know that he would commonly take a dump on stage... hence the term I have coined 'GG tail'.
I had to find a bathroom quick so I could grow a GG tail.
I stunk up the bathroom when I grew my GG tail.
