A very bushy and thick patch of hair usually covering a girl's vagina. Can be combed and/or parted, but is usually frowned upon by men. Some men have even been known to break off a relationship because of a muff.
"Yo, Sandy has this crazy muff. It's so disgusting."
"Yeah, that's why she got nicknamed Grassy Meadows."
