What about a woman's appearance suggests that she is a bunny boiler? Would you be able to tell that a woman...?

To find out the concept of bunny boiler you need to watch and study the film "Fatal Attraction" with Glenn Close and Michael Douglas. As the film loosely suggests you won't know until it's too late. Oh men be wary "Never trust a big and a smile, that girl is poison!". Seriously do your homework on the partner you intend to be with to avoid any painful episodes. ( how do those women go to the toilet and wipe dem selves afterwards wid dem nails? OWCH!)
