cari istilah yang lo mau, kaya' sex:
 
1.
When something really bad happens. Comes from suck and in this case it is sucking something big and fat. Used in the worst of situations when not much else can be said.
Doctor: I'm sorry, but you only have a few more months to live.
Man: Damn. That sucks a fat one.
