A sweaty slimy scottish creature that usually comes out of it's rape cave when it smells fresh young pussy meat. Usually tend to target young vulnerable women and drags them back to it's lair.
Damn thee young fool, be wary of the wild Gillin. For he smells thy young tender pussy flaps, and their sweet odour.
