So I'm avid role player, and I noticed how full body to some, it has two definitions. The more accepted version being spherical inflation, the other is like an exaggerated blow up doll, maybe to blimpish proportions. I think we need to clear the air and separate the two terms. I am not sure what you might call the latter term is all.
From a derpy inflator who runs into this conundrum a lot. X3
I usually use spherical and full-body inflation as the same meaning but I think full-body should be used to specifically refer to the latter, since "full-body" would not only imply the inflation of the belly but also the arms, legs, breasts and sometimes head. Spherical inflation should use its own definition, even though so many just call it full-body, since it's a kind of belly inflation (though takes up the whole torso, not just the belly). I'm not gold with definitions, to me everything has several, but I suppose that's my take on full-body/spherical inflation.
