It's from the movie Billy Madison. There was a family of bullies with the last name of O'Doyle, and everytime they picked on someone afterwards they would say "O'Doyle Rules". They eventually had an incident with a banana peel, but you'll have to watch the movie for that one ;)
prob the biggest reason i don't like these type of comments is that the replies will really never be interesting. there is no way for them to be, by nature of the parent not being interesting
and i'm not even shaming you, but finally creating words for my thought when i'm irritated heh
edit: by nature of the parent comment, you are able to unfold the origin of the name (and there was no reference elsewhere). ok, fine then :P
