A very unsanitary and unsightly act, usually undertaken to disgust and/or attack another being. The Dirty Lady Lasso involves a woman who is currently experiencing her period to tug away at the inserted tampon, and remove it for the world to see, complete with blood, mung, and other hideous substances it collected while inside the female. The lady then twirls the bloody object around, much like a lasso, and then throws said item at unsuspecting/undefended victim. First known case of the Dirty Lady Lasso was performed by the infamous Transsexual Kristina K.
"Yuck Man. I don't know what I did but before I knew it she did the old Dirty Lady Lasso and the the next thing I remember was having a bloody tampon land and soil my clothes."
