Basically when I'm bored I come up with ways to amuse myself, my joy of late has been "casting spells" in public. And by "casting spells" I mean passing gas.
The joy of this, of course, is to cause as much damage as possible without getting caught, which a silent walk-by accomplishes.
I've borrowed some terminology I use to help notify my friends of my desire to cast spells and which spells I shall be casting.
Casting Spells - the act of farting in public
Expelliarmus - used for disarming one's opponent, in this case, used for disarming a fully loaded ass. A well placed expelliarmus spell will cause sniffing and glances around for the culprit.
Crucio - One of the "unforgivable curses", crucio curses depend on the damage done. Usually causes a sour look, sniffing, and the desire to leave the area immediately. A experienced caster can cause dry-heaves with a powerful enough crucio curse.
Avada Kedavra - The mother of all "unforgivable curses" it comes from the aramiac phrase "may it be destoryed". Those who cast the Avada Kedavra know well to leave the area with haste as total destruction is caused and those who walk through it's wake are in great peril. Symptoms that AK has been cast involve gagging possibly leading to dry-heaves/vomiting, immediate vacating of the area by all people, and possibly fainting and bleeding around the eyes.
While there are no known defenses for these spells, always look for the warning signs from the caster including, but not limited to, running and giggling, carefully watching an unihabited area and of course, those casters who have not yet mastered the ability to cast silent spells.
