Well, it's a 'silly made-up term' with enough usage over a long enough period, (it dates from at least the 1920s), that you can expect to find it in most decent English dictionaries. I also can't really think of a better term for that particular hybrid, given the constraint that it needs to be distinguished from tigon, (that's when the tiger is the father, they are much smaller than ligers).

The others don't have quite the pedigree, (zorse is about as old, but is much less common due to the rarity of zebroids in general and their lack of the "WOW! that's a big cat!" factor).
