a whole heckuva lotta bit
It’s when you’re not just a little bit tired. You’re a whole heckuva lotta bit tired. Like you’ve been running for three days and your brain is made of soup.
I had to do homework for three hours. A whole heckuva lotta bit tired.
I woke up at 6 AM. A whole heckuva lotta bit tired.
I ran a mile. A whole heckuva lotta bit tired.
