A butthole that is so beat up and streched out it looks like a worn out vagina.
John has some severe butt lips.

Buttlips are the part of the butt cheeks that hang below one's shorts... Just that little bit of cheek that is not the front lips, just the butt lips.
Every time my girlfriend wears her running shorts I can see her buttlips hanging out.
