onomatopoetic variant of:
- The Three Stooges' Curly spinning around on the floor in a circle
- That doofy audience cheer from the now defunct Arsenio Hall show
used as a semi-enthusiastic cheer regarding an accomplishment of minor or even dubious importance
delivered in the same subdued manner as a quiet chuckle
Managed to get a flu shot today (beginning of the flu shot season this year too). Woob.
