During yoga class, our instructor clam coughed; it sounded like a small trumpet and some folks applauded.

An action normally associated with hacking up copious amounts of flem, snot or other horrendously disgusting and slimy things.

Not a pretty cough.

Definitely one of those coughs that make you feel bad about yourself after one slips out in public. Kind of like a clam who opens his mouth under water. Only instead of cute bubbles, it's totally heinous boogers
