Halusian Gulp

Does anyone know the origin and meaning of Halusian Gulp?

Tom Wolfe has used in his writings (one example may be found in The Right Stuff).

Did Tom Wolfe know the Malaysian language? Had he traveled in Southeast Asia? Try Googling "Halus Gulp." Lots of hits, lots of stories, some involving elves, some frogs. Halus has lots of meanings, including names, but not many involve Gulps. SS
