It is difficult to represent that elliptical illocution though. Either {ge'e} can represent an illocution or evidential as well, which makes it extremely vague, or it can only express UI1-type emotions, in which case it isn't useful here. On the other hand, there may not be enough justification to create a cmavo to represent it.
Or perhaps we could just take a page from Curtis and create a ridiculously long cmavo so as to not take up space that we might want to actually use, e.g. {ju'a'o'e} :p
