The posture that one takes while attempting to use a public toilet (Gas Station, Grocery Store, Resturaunt, ect...)while trying to avoid making contact with the seat. On occasion with lower pulic toilets, one must also brace them self with one hand against the wall to avoid falling in. Also known as a "Floating Susan" when executed by a female.
They were out of ass gaskets in the stall, So Stan had to attempt a risky "hovering alfred", before he shat himself.
