It is something seen on many Asian sites, or at least more often than not. When many men come on a woman's face (and I am talking MANY men), this is referred to as a bukake.
Yeah, the way I understand it, the Money Shot and Bukake a kinda the same thing. It's just that the Money Shot only needs one guy, while Bukake needs many guys. I think also Bukake involves stuff like many guys filling a cup or something with cum and then forcing the girl to drink it. I'm no expert, though.
A "money shot" is (of course) a cum shot. Bukake is a group of men that all jerk off on a woman's face. A lot of men. A lot of cum. Sometimes you have the woman drinking all the cum out of a glass and other fun and games.
You know, I'm a women, and I am not exactly sure that I would want that done to me ..... I mean one guy I can deal with, two maybe, but many? and drinking it of a cup? hmmmm ... seems like something more for the men than women
