Father Brown

When someone pulls a "Father Brown", the person uses a really long, complicated explanation for a whodunnit murder, when they are the actual murderer.

Robert Wagner pulled a "Father Brown" for his side of the story for his wife's death.

Brown Rocket

It's pretty self explanatory… firing a rocket and coming out brown…

Pretty much when you fuck a butt hole and you pull out and you have shit on your dick.

Bruv, I gave that chick a hell of a brown rocket last night!
