How to get down with/embarrass the kids ;-P

Wear low slung jeans.
Chew gum with your mouth open.
Wear a baseball cap back to front.
Play music too loudly.
Dress like your daughter.
Dress like your son.
Touch fists as a greeting.
Have a 'young' haircut.
Play games on your mobile.
Use 'teen-speak' like 'chillax' and 'awesome.

but the kids are alright ;-)
