A fitten is a sexually attactive human-being of the female sex. A contraction of the words 'fit' (meaning attactive) and 'kitten' (a suitable noun to complement 'fit'), fitten can be used in a variety of contexts.
For example, "dude, that girl is a fitten", "I don't know who you were talking about, but that girl's more of an uggo" or "bruv, that girl you were talking to was a fitten, so why did you leave the party with the minger?". Not to be used for grandmas, cave-dwellers or mingers.
