OPP 

Over Protective Parent

A Mother or Father who is a bit over cautious of their child's safety.

Walking them to high school everyday.

Making them wear a crash helmet and knee pads when they go out in Heelys.

Taking them out shopping, up to the corner shop.

Blocking Facebook and msn from the internet (all your classmates Facebook pages could actually be a mob of stalkers and rapists who are trying to kidnap you)

"Hey Nathan, want to walk me back to my house after school?"

"I can't, my mum's picking me up."

"Call her and tell her you're walking home with me."

"She says I have to have at least one responsible adult around at all times, especially out in the street."
