This usually applies to homework: When you are swamped by homework and it is whipping you, in other words:
You have too much homework and you don't understand it.
You know that feeling when your eyes start to blurr and you think you're going to fall asleep? There you have it.
I can barely stay awake: I'm womped!
I need to take a break, this homeworking is womping me. >>>oops, whoever wrote that was womped<<<
