As Urban Dictionary is to Webster's, Brown Sign Language is to American Sign Language. A collection of lewd or outrageous terms communicated in 'slang' sign language, BSL is used by deviant strands of the hearing-impaired community and their miscreant, funk-loving friends. Using common-sense hand gestures to represent graphic activities, BSL is absolutely inappropriate for respectable family settings.
Todd and Eric were telling jokes about wet dreams in Brown Sign Language at the wedding reception when they realized the bride's parents could read their signs from across the ballroom. Fortunately, the bride was a patient woman and eventually forgave them for using BSL in front of her family.
