My name is SCOUT!

Scout just recently learned how to say her name more clearly; emphasizing the "Sc" part of it. A hard to thing to master apparently. She is very protective of her name, and her brother is well, quite determined to bug her most anyway he can. Currently, Lincoln is adding "poo" onto everyone's name and pretty much every word that comes out of his mouth. While I continually grimace each time it happens, or chastise him and the like, it still happens. So, now I try to ignore it. Either way, I'm sure I'm reacting incorrectly. So, while Lincoln continually calls her Scouty-poo and poo-bum Scout, she obviously reacts harshly. The other day when I said "Good morning sweetheart," she scowled at me with her famous Scout-scowl and screamed at me, "MY NAME IS SCOUT! MY NAME IS SCOUT! MY NAME IS SCOUT!". It took everything I had not to laugh hysterically, but I did laugh. That didn't go over well either.
