yuckmouth 

1970s era commercial jingle about the need to brush your teeth to avoid tooth decay

They call me Yuckmouth
Cause I don't brush
No I like my teeth like this

They call me Yuckmouth
Cause I don't brush
How's about a little kiss?

Got some beef in my teeth
Got some chicken too
Ouch! That's a cavity
Hey, that's new!

Well if you don't brush your teeth
Then yes, you too
Will be a yuckmouth

Don't be a yuckmouth!
