BIFF

Mainly a universal word for many other words,including serveral categories. Biff can be used at any age, as it is not profane or racial. This word can be said heard in the streets of Pennsylvania and hopefully spread further around the world. Biff substitutes for many slang terms used, or words you wish not to say in a conversation. Also a code name for unwanted words.

That hot chick has a nice BIFF!
