You Mean You Already Know What That Means?!

I'm sitting in the living room checking some stuff on the internet.
My 13 year old daughter is watching a movie next to me.

Suddenly, I hear "You gave me crabs."

I sneak a look at her to gauge if she understood what it meant.
To my horror, she's laughing - in t.o.t.a.l. u.n.d.e.r.s.t.a.n.d.i.n.g.

I say, "You know what that means?"

She nods sagely and rolls her eyes at me as if it's soo yesterday's news.

In my attempt to be totally uber-cool, hip and not at all show an ounce of discomfort, I reply:

"Hey, that's not fair. I'm supposed to be the one who gets to tell you all that stuff!"

She laughs her head off.
(phew)

simultaneous internal head chatter:
Omg omg omg omg. Wonder what else she knows about.
Gasp.
