How Do You Spell BEING UP UP?
Pronunciation: [bˌiːɪŋ ˌʌp ˈʌp] (IPA) 
The phrase "being up up" may seem confusing in terms of spelling, but it's all about the pronunciation. In IPA phonetic transcription, it would be written as /biːɪŋ ʌp ʌp/. The first "up" sound is pronounced with a short vowel sound, while the second "up" is pronounced with a schwa sound, which is the mid-central vowel sound in the middle of the mouth. This is why it's spelled differently in the phrase. So, while the spelling may seem unusual, it accurately represents the pronunciation.
