Half-Blood Prince

Your member, engorged with blood when you look at the curves of the now-legal Hermione.

Emma Watson gives me a "Half-Blood Prince".

half blood prince

A semi-boner; a penis that is engulfed with half of the blood required for a complete erection.

I got this awkward half blood prince during math class today, but luckily it subsided when I concentrated really hard on David the Gnome.

A textbook (usually old) with lots of very helpful writing on the inside of it.

The name comes from the sixth Harry Potter novel/movie.

Half Blood Prints

Notes, highlighting, or underlining from a past reader that is found in a library book or a used textbook and helps the current reader. Like the helpful notes Harry Potter finds in his Potions textbook in the sixth book/movie.

"Man, taking notes last night took forever!"

"Not for me. I got some half blood prints up in this copy of Grapes of Wrath. Everything I needed was already highlighted."
