How to say these in Korean
how would you say these sentences in informal Korean?

-You know me so well
-You're winning
- i messed up
- Are you cheating on me?
- since when?

Also.. Is there a way to say "excuse me" informally? Like if your friend is in your way and you would like them to move, what would you say?

Answer

You know me so well - 너는 나를 잘 알아.
You're winning - 네가 이기고 있어(prensent tense). 네가 이겼어(past tense)
i messed up - 내가 망쳤어. 
Are you cheating on me? - 네가 나를 속이고 있는거야?
since when? - 언제부터?

excuse me -  Like the situation you said, we can say 실례합니다.길 비켜주세요.if we say it informally,비켜 봐.it sounds impolite.

You're winning: 너가 이기고 있어
