Short for 'crossbow
', usually used in the context of RPG
s or FPS
es in which such weapons are used. It is a typing abbreviation and thus is most often seen under conditions either where fast typing is more important than accurate spelling or where the people talking are just lazy typists. The spelling comes from the idea that the letter 'x' looks like a cross and thus replaces the syllable 'cross' in the original word (much like the more common 'xing
' for 'crossing'). It is usually pronounced either 'CRAWS-boe' (ignoring the spelling change) or 'EHX-boe' (pronouncing the 'x' by its letter name).
