We say 'I am zapped out', meaning i am tired, or you can say 'you look zapped out' meaning the person you are talking to looks tired. You can also shorten this and just use zapped which means the same thing 'I'm zapped'. To 'goof up' means you made a mistake, again we tend to contract it to 'goofed' and we might say 'I goofed' or 'he/she goofed'. These are not bad words, you will probably hear them used in any/most American TV shows. There are American phrases which have been partly adopted into British English as slang.

I'd even say these are a bit outdated. If you know the meaning, I'm sure you know whether they count as swearing or not! ;) It's better to focus on your standard English (yes, you are making basic errors) instead of trying to deal with the colloquialisms.
