For some one to look at you the wrong way, a dirty look.
*talking to friend walking in casino* "Hey see that tool over there? He just mean mugged me! Lets hit him up!"
adverb. Relating to the unpleasant and often downright grumpy action of frowning and/or lightly non-verbaly disrespecting someone in order to make them feel insecure.
As I walked into the room with my new attractive boyfreind, whom I spent most of my time with nowdays, I could help but feel "mean-mugged" by my ex-boyfreind, Brooks, who was drowning his sorrows in alcohol at the end of the bar, becuase he was recently fired from his job, and has resorted to selling cheap elevators in Boston.
