Whistle booger

The cause of an unfortunate situation when an unsuspecting fellow exhales through his nose only to produce a high pitched nasal whistle due to the existence of a crusty booger lining the nostrils. The noise is so shrill that one tries to sniffle to play it off, only to then issue several smaller whistles succinctly.

As allergy season looms, the nasal passages becomed lined with mucus crustaceans and every breath beckons the arrival of the whistle booger songstress.
