Average, "I dunno" sort of expression. Instead of a word you'd say 'bleh'.
Well, it was just kinda... bleh.
Short for "Hajimemashite" - Japanese for "Nice to meet you". Adopted as a greeting and then shortened to "Hajime". Sort of said under breath; not like "HAJIME!!!! OMG OMG!!".
>Hajime, so what's going on?
>Stuff.
