Film

Probably the most famous, from Die Hard:

Gruber: Who are you? Just another American who saw too many movies as a child? Another orphan of a bankrupt culture who thinks he's John Wayne? Rambo? Marshal Dillon?
McClane: I was always kinda partial to Roy Rogers actually. I really like those sequined shirts.
Gruber: Do you really think you have a chance against us, Mr. Cowboy?
McClane: Yippee-ki-yay, motherfucker.

In Gladiator, the protagonist has a horse whose name is "Trigger" in Latin.
