This is an answer to a question. 

Yupee is not generally used in Hungarian. Perhaps children say this when they are happy, but the everyday use of this word is very limited. I have never heard "yupee" when peple said good-bye to each other. 

Teszek means "I am placing stg to/on/in stg". So it is not related to "again" in any way. Other uses include teszek egy próbát - "I'll give it a try". 

"again" = megint, újra, ismét
