When you're at work and people keep stopping by to drop off more shit for you to do. It just keeps coming and you can't dig out.
Much like bukkake but you're buried in work instead
You: Hey hun, how was your day?
Her: I got shitkakked today, everybody needed something and it just wouldn't stop.
You: Well, that's a hell of a story, now make me a sammich!
A reaction upon hearing/seeing something humorous/suprising, where a person eating or drinking spits out their food or beverage. The term derives from a mix Spit-Take and bukkake. "Spittake" is pronounced "Spi-ta-kay".
