Pretty much any sort of irritating situation is worthy of a "bitchface" from Sam Winchester of Supernatural. Sam tends to make this face a lot in the presence of his exasperating brother, Dean.
According to Urban Dictionary.com, the definition of "bitchface" is the following:
A face that somebody gives when they are angry/annoyed/irritated. Meant to ward off any bystanders who will further bother said person. This is a look that can kill, if need be.
