1. To dramatically over wiggle. You can find the wiggliest in all of your children.
2. To shake your groovethang to the max. Unlike squiggle, which is to squirm, wriggle, write, paint hastily or scribble, being the wiggliest, you can ensure that you will always leave the party with a hot date and get 'some'.
You, Fracis are the Wiggliest child on the planet.
