See also "beer goggles". A certain level of alcohol intoxication renders otherwise attractive people who are annoyingly talkative, less annoying. An ugly annoying person would require both beer goggles and beer muffs. AKA "beer plugs".

While having doggystyle sex with a gal, and you grab her ass cheeks and spread them to take a look at her booty hole, you notice strains of hair all around her asshole.
Dude, I was dogging this chic last night and went to check her asshole out and she was packing a total ass muff.

The style in which a female trims her bush. Variations include but are not limited to pencil muff-stache(landing strip), handlebar muff-stache(well-styled), and Fu Manchu/Walrus muff-stache(needs attention).
Dude 1: What's with the lobster face dude?
Dude 2: I've got a mean rugburn from goin down on your mom last night. She needs to trim her *muff-stache...seriously dude.
*In this example, muff-stache could be substituted with Fu Manchu or Walrus.
