New Orleanians have a hodgepodge of slang terminology often used in bounce music. Here is some of the "slanguage" defined:
504: The New Orleans area code, used in terms such as "I represent that 504."
Beaucoup: A lot, from the French, as in "that was beaucoup funny." Pronounced "bookoo."
Slugs: Gold teeth. To be "slugged up" is to have a mouthful of gold teeth.
Trill: An adjective that means to be real and true.
Ward: A section of the city.
Whoa'na: Uh oh.
