(pronounced sitch-in): when any bad situation, but usually work- or relationship-related, goes from difficult to an all-out fiasco.
Work: I forgot to take off for my anniversary tomorrow and my boss just dumped a 3-week project in my lap and told me to have it finalized by tomorrow at 2pm; I am going to have to stay here all night to get this done. I am in a serious sit'n, my boyfriend's going to kill me.

Dating: My fiance told me he would leave his wife, he still hasn't, but he did tell her about me. Only now, she's calling me all day and night crying into the phone and hanging up. His solution is to ignore her until he can find a new apartment and move out. This has turned into a ridiculous sit'n.
