Today's word is awesome, because it combines my three favourite type of words: 1) "OMG, there's a WORD for that?" 2) Made up words! 3) Totally useless in non-specific conversation topics!
Calculator spelling - a technique of spelling words by reading characters upside-down from calculators equipped with certain kinds of seven-segment displays.
Calculator spelling has been prevalent ever since the first segmented display calculators were available, and ever since the first student learned that 5318008 spelt BOOBIES upside-down. The term 'BEGHILOS' comes from the letters, in alphabetical order, which can be made using seven-segment numbers - 83941705. As such, it's also sometimes called BEGHILOZ or BEGHILOSZ as a Z is also available.

Legless eggshell oozes oil
Elegize his loss
Hellish shoe is beige
I slosh soil, slog hill
Hobble, oh high heel
