a most severe
camel toe...
the indentation that extends upwards from the vaginal area that can be
seen through a females trousers. in general, the "aftershock's" measure via a thick trouser material (I.E. JEANS) that creates a more visible and deeper indentation denotes a more gratuitous pussy size.
the pussy itself can be described as a severe earthquake in this instance and the severe
camel toe is the aftershock. thus the aftermath is the aftershock created in the pants of the great big pussy.
