When a person enters a group or into the vicinity of others, deliberately passes gas, and then departs as if nothing happened.
Oh my gosh! Do you smell that? I think Bill from accounting just gas passsed us before he left. We should invite him out for a power lunch and get him back.
If you have to pass gas, and you have to save it for later.
Person 1- UGH i have such wretched gas.
Person 2- Query, do you have your gas pass handy?
Person 1- NO, gonna have to just let it loose.
