"Ecce homo qui est faba" is a phrase from a British comedy show called "Mr. Bean." In the show, Mr. Bean is a character who does silly things and makes people laugh. One of the things he does is pretend to be a statue and stands very still, so people think he is just a statue.
The phrase "Ecce homo qui est faba" means "Behold the man who is a bean" in Latin. It's a joke because Mr. Bean's last name is Bean, and he looks like a little bean with his small, round head and skinny body.
So, when people say "Ecce homo qui est faba," it's a way of pointing at Mr. Bean and saying, "Look at that man! He looks like a little bean!" It's just a fun way of acknowledging how funny and silly Mr. Bean is as a character in the show.
