A Slughorn is pretty much an undesirable woman with a loud mouth. Whether she is fat, ugly or a straight up retard, she must be undesirable.
However, in some circumstances a desirable woman
may be called a slughorn. For example during times of drunken
frustration or when she has just
pissed you off.

Leon had no
choice but to call her a Slughorn.
