look up any word, like the eiffel tower:
 
1.
The female equivalent of a ladies man. A girl who gets along with all the guys. Can imply a degree of flirtatiousness but absolutely not a whore or slut.

When used with the article 'a', fexx can sound like "affects." To avoid this, fexx and fexxy must be used with 'the.'
Look at her at that table of all guys... she's such the fexx.
