I don't think that's standard anymore. The terms "total utilitarian" and "average utilitarian" are generally recognized, where "total utilitarian" means what you called "utilitarian".

"Average" and "total" utilitarian are just two different ways of specifying what "aggregate" means though. To my knowledge, none of the standard utilitarian positions (outside of lesswrong) say "maximize your own values." (I'm willing to be corrected here.) To LWer's, it's not confusing, but to most outsiders, they'll probably come away with a different message than you intended.
