A variation of the "Roman Spider Dump" mixed with a "Double Blumpkin." Two males face each other on the toilette while taking a dump, a third person hangs from the top of the stall like Spiderman and preforms oral sex on the other two. This act is most commonly performed in the washrooms of Mellon Arena between periods.
Star: "That chick sitting in front of us is disgusting and her crazy husband thinks the Leafs are offside every time they cross the blue line."

Murk: "Dude, I think I saw them and the usher preforming a Pittsburgh Spider Blumpkin before the third period in the can!!"
