"Plox"

From Euphro

The word "plox" stems from the word "plx"; which originated as a typo for "pls", which is an abbreviation for "please."

It is used jokingly by many players of EuphRO, to ask for heals and such, in the form of something like "HEAL PLOX". Sometimes it is also spelled "pl0x", with the number 0 in place of the letter "o", in a mock form of 1337 (leet).
