noodling around
the act of doing things for no purpose other than entertaining yourself and/or others
We had big plans for that day, but we ended up just noodling around and setting fire to little children. It was the best day of my life.
noodle around
wandering/exploring with no set destination for no specified amount of time.
ex: "i'm bored." "you wanna go noodle around?" "sure!" then, you may walk down to your nearest main st. or bamboo forest.
