Chockablock full?

[housenuts]

Can I use the term 'chockablock full' in an academic essay?

I love this term and use it alot but not sure if it's ok for an essay. My course is kind of a joke anyways

Germanic Studies 487 - A Cultural History of Vampires in Literature and Film

i am writing a 3 page paper on Bram Stoker's Dracula and I want to say "Right from the beginning, the movie is chockablock full of the colour red." i think i'm gonna do it regardless, just wondering what others think.

as for the term, if it's not in your vocab it should be.

ie.
bob: how was the bar last night?
frank: awesome, it was chockablock full of hotties
