Foul Mouth is another of a series of prank spells created by one of the most incorrigible students in the history of the Great School of Magic. Less popular than Rude Conjuration due to its requirement that prankster and prankee must come in physical contact at some point, it nevertheless pops up memorably at least once per school year, most infamously several years ago at a graduation ceremony that ended rather badly for all concerned.
The victim of the spell will find themselves constantly spewing profanity in a loud tone. While they can also speak and cast spells while under the influence of foul utterance, all non-spell casting speech is peppered with colourful obscenities - ie "I'm can't #$%!@ help it, you #$%!"
While the victim has to curse non-stop, which may pose difficulties depending on the social situation, they won't put themselves in immediate physical danger by doing so; A victim holding their breath underwater is unaffected until they can surface. Of course, that cuts both ways: A victim cannot choose to hold their breath simply to stop speaking. If the victim is not in a situation where they normally would be required to hold their breath, the spell induces them to speak.
Foul Mouth can be cast in conjunction with a permanency spell.
Material component: A few drops of vinegar, which must be rubbed on the victim's skin.
