Muff Gruff

The 5 o'clock shadow girls get after a few days of not shaving their pubic region.

If you think I'm eating that with that muff gruff going on, you got another thing coming.

Gruff

When your girlfriend will act as a dog for you ( You can take this as sexually as you'd want )

"Do you want me to Gruff honey?"

gruff

1) A crusty exterior of an object

2) Random blabbering while laughing

1) Ugh, dude, my finger is gruff

2) She kept trying to tell me what happened at the football yesterday, but she was talkin' gruff.
