maybe you do. But it is not something we say much on the UK.You appear to mean "tough."
Collins Concise English Dictionary © Harper Collins Publishers::
- (transitive) slang to stand firm, hold out against (a difficulty or difficult situation) (esp in tough it out)
"Suck it up" doesn't only mean "just accept this." It can also mean "deal with it (stop complaining, stop whining...)."(snip)
This memorization is a specific task that must be done in order for the student to pass. I think Jenson's "deal with it" works, as does Suzi's "get on with it". Mathman's "suck it up" (very informal AE slang, to be used only with a friend), which means something a little different (just accept this) is also an appropriate comment. Personally, I'd probably say, "Hey, it's required. Just do it."
I guess it is just AE then. I've heard and used it all my life.I agree that rough it means something different. My first thought was "Just live with it/get on with it!". I wouldn't have understood what was meant by "suck it up", by the way.
