The satisfaction you get when you finish something so tough it makes your brain do the cha-cha.
After finishing that math exam, my brain did the cha-cha and I cried happy tears.
When I finished my 10-mile run, my brain danced and I screamed like a rockstar.
After cleaning my room like it was a war zone, my brain did the cha-cha and I got a snack.
