Just Relax and have Fun with it.
Its not recommended at school gates.
Peace through peace.
As opposed to hanging in, or maybe hanging ten, depending on the context being hung can be good or bad. Lol.
When you're letting it "hang out," you're being yourself....almost to rare form. The release is therapeutic, because you're not shouldering the stress that comes with holding back to conform to your surroundings.
Just don't get arrested LOL.
