How do you give your mom a wedgie?

You say this to your mom "hey mom can I show you this new cool trick" she will say yes if she says no she is busy and ask later. So if she says yes you tell her to come over to you she will say okay then you say turn around do her butt is aiming tou you then say close your eyes and tell me when your ready when she says ready pull her panties up so hard and high then run away or just say how was the trick mom?
