look up any word, like bae:
 
1.
A disinterested frustration with something overwhelmingly negative or boring.
1. "I could really pay attention better if I wasn't feeling so terri-blah about everything today."

2. "how am I doing? fucking terri-bla bro, I'm so over this shit..."

3. "I don't think Terri-blah is a word."
