A fusion of the words "but" and "uh". When you say but, quickly followed by "uh". Difficult to differentiate from the word "butter". Often it sounds like the person saying it has momentarily stopped thinking about what they were talking about and began fantasizing about butter.
I went to dinner at O'charly's with Ella last night. It was difficult to tell if she said "buttuh" because she needed to think or if it was because she was excited that the dinner rolls arrived.
