Oh for crying out loud. Toddlers cuss if they hear the words enough. Heck, they'll say anything if they hear it. My daughter, now 2, spits out random words all the time. Today she's with my mom, sitting on her lap, puts a finger on a nipple and says, "Nana's nipple!" Over and over again.
My other favorites that I've taught her: Grab a cell phone and yell into it "Where's my money?!"
Hold random object over her head and yell, "By the power of Grayskull!"
"Booyah!" is now her go-to one-word exclamation.
Ok, so I might not be the best parent.
