An activity involving matches being simultaneously flicked and lit. The matches are held like paper footballs against the striker on the matchbox. The middle or fore finger is then used to flick the match. This causes the match to be lit before flying off the box. Often played as a game with friends.
Never go dillywacking in the woods. You could start forest fires. Also, be careful not to dillywack into someone's hair.
