It was "The Electric Horseman" with Robert Redford, Jane Fonda and Willie Nelson.

Willie (Rodeo rider Redford's sidekick) when asked what he was going to do after Redford ran off with the horse, states, "I don't know about you, but I'm getting a bottle of tequila and one of those Keno girls that can s*ck the chrome off of a traler hitch and kick back"
