Alternatively, maybe "nyepong" is a typo or a misspelling of "nyopot" (to take out) or "menyumpal" (to stuff into the mouth). If it's "nyepong" as in inserting a sponge into the mouth, the scandal could be a female teacher doing that, and then wanting to remove it. The "exclusive" part might be referring to a special method or setting, but that's unclear.
