Boy Lingo

Ok... I obviously need to get up on my boy 'lingo:'

Tonight:

Mom: Christian, why do you have on two pairs of boxers?
Christian: What?
Mom: Why do I see two pairs of boxers on you?
Christian: What do you mean?
Mom: Come here. (pulling up on the second pair of boxers)
Christian: Oh, for protection when Alec pants me.
Mom: What's "pants me" mean?
Christian: You don't KNOW what pantsing means?
Mom: No. What is it? (bending over and loading the dishwasher)

At which point I found my shorts around my ankles and my son running away.

Christian: That's what pantsing means!
