Brit/ Amer word booger

[blenberry]

Hello... 

It seems this is the proper forum in which to pose my question. 

Sorry to bring down the level of discussion (lofty concepts such as 
fractals, etc) but here it is:  In the British versions of HP, does 
the word appear as "booger" ("troll boogers", "booger-flavored") or 
is that an Americanization?  I notice that in the film it is 
pronouced "bogey".

Thanks,

Barbara
