Whatever sexual innuendo grosses you out the most is your "Howie Sandwich". It's that one spectacularly disgusting sexual reference that has been burned into your brain in a way that you are never the same person again. It's a sexual innuendo that is so crazy and odd that you won't ever forget it - even though normal people would pretty much give anything if they could forget it. Discovering the next "Howie Sandwich" is a game only the bravest perverts will play. It's the perfect phrase to describe what your favorite dirty minded friend would like for dinner. The phrase is derived from the mental image obtained when "Howie" is sandwiched between two broads.
Go home with that fucktard? Are you kidding me? Who knows what he'll do to me! He's a Howie Sandwich!
