Is the act of placing a suppository in the anus, via the Schlong.
I was backed up severely and had tried every option I knew. My buddy Jeremy suggested a suppository, but I dated a girl who once stuck her finger in my ass and cut it severely due to her art of shitty Manicuring. I called my buddy Matt to see if her would put it in via Schlong, which he did and we decided to call it a Sclongpository. It felt better than I thought.
