A bean can be used to describe someone in a loving, weirdly romantic way for nerds/freaks that read too much fanfic and have no friends.
It can also be used to describe someone that simply looks like a bean. This person is also usually asexual with a bean shaped head, and just the overall non-literal but hilarious appearance of a bean. It tends to be a nickname.
Bean can also be sexual meaning the clitorus. It depends on your dirty little mind.
There is also the more specific meaning like baked
beans or green
beans. But I'
m sure you don't care about them when you're looking on urban
dictionary do you darlin?
