To look at someone with a mean look
She just mean-mugged Janos
door D.Irvin 21 oktober 2008
The sexual act during which the provider of oral stimulation momentarily removes the penis from her/his mouth to glare at it as though they are angry at, or absolutely loathe said penis. The stare down is completed when she/he spits on the penis and continues the fellatio in a vigorous manner.
"hey bobby, check out this hot blowjob scene. I love it when she mean mugs that stud's cock"
