The 'Boobies Of The Day' hint is Potter POOTER.....WTF?!
Yes, pooter is part of the slang phrase "pooter cooter" which is slang for the vagina, but since only the word POOTER was used and not pooter COOTER, then the only thing it can be referring to is Emma Watson's asshole and...FARTS. Pooter means the asshole and if poot means to fart, then the pooter is the thing that creates the farts.
So the 'Boobies Of The Day' hint, is referring to farts. That is an awesome hint!..........WTF?!
