Looks like a variant on hooey, which the OED defines as:
Humbug, nonsense.
It’s marked as slang that was originally from the U.S. Also so labelled is phooey, which is given to mean:
An expression of strong disagreement with or disapproval of something said. Also as sb., applied to the thing said: nonsense, ‘baloney’.
Both terms’ first citations are from the 1920s.
1924 P. Marks Plastic Age 100 — My prof’s full of hooey. He doesn’t know a C theme from an A one.
1929 Sun (Baltimore) 11 July 11/1 — Girls are described as weenies, janes, dames and broads. A mad-man is phooey, crackers or blooey.
Of hooey it says “Origin unknown”.
