Hello,
I answered as "All right you win. I promise I won't bring it on again. Why don't just we go white water rafting instead?" I have heard in movies people say, "Bring it on". What is the difference between "bring it on" and "bring it up".
With Regards,
Santak

Hi,

'Bring it on' is an expression that can be used to encourage someone to do something. It's similar to an expression like: Go ahead and do it! 'Bring something up' is a phrasal verb and suggests 'mention' or 'introduce a topic in conversation'.

Yes, that's right. You can find other phrasal verbs using 'bring' shown in the piece I've written for site under the heading ' bring'.
