Unbeknownst to some, the word "superfisal" means grossly incompetent, so much so that the word is used only when the intent to kill the recipient is at it's strongest point.
I foresee a meeting between the two of them in which "your girl" gets her abdomen speared with a broken pool cue, and she ends up a vegetable - a tragic tale.
I'd advise her to take extra caution when dealing with this harlot.
