My Bff: Hey do want any coffee?
Me: Yeh, of course.
My Bff: Ok which one?
Me: You know... the black one.
Me: Like my soul...
My Bff: Jeez you ok?
Listen up, buttercup. This joke is all about dark humor. The person is saying their soul is as black as their coffee, which means they are probably super bummed out. You probably don't know what a soul is because you're a soulless ginger.
