Referring to any individual that is ugly!

a gargoyle is someone that preseves virgin faith.. hence why they are on alot of churches.... this can be from the creation of a new religion to preserving a womans chastity
and if you are really experienced her virginity as well...
that is why they look hideous and eventually turn to stone
because of what preserving a virgin or virgin faith can do to you...

also a person with a ugly face or facial feature

a stone statue that in fantasy is said to be a strong demon creature that can glide but not fly and at sunrise must roost and become stone.

Its reference to a female's booty that you cant see right away. It can be a small & tight butt or (i prefer) a big & ferm booty.
Also a gargoyle is the butt version warlock (see warlock)

the act of perching one's self upon the toilet ass naked to enable gravity assisted excrement evacuation
warning:
during extremely loose bowel movements the gargoyle should not be attempted due to splash back results and ankle dirtyage

note:
toilet seat life greatly diminished by gargoylage

When a chick gives a guy a blowjob while he is standing and she is squating in front of him. After he comes, she lets the jizz run out of her mouth like a perched gargoyle with rain water draining from its mouth.
