When "fuck" just isn't enough.
When it's hard to get out of bed and you finally swing your feet out first, "fuck-yah" provides added thrust. Pronounced by dragging out the last syllable, "Fuck yaaahh"

Also used on the way down when jumping or falling from something high. Fuuuuk-yaaaahh.

When barely suppressing anger, bare teeth and exhale while spitting the word out. "This is my second parking ticket this week! FUCK-YAAAAHHHH.
