Here follows a brief
history of reg ;)
AutoVoice, the God of #jj2, has a feature that allows him to record random phrases
people say and spit them back out as an autoresponse later on. So one morning #jj2'er Disguise said reg ;) meaning 'regular'.
Later, on a particularly sleep
baked night in #jj2, AV's autoresponse script was activated, and for some reason 70% of the time the only response was reg ;). Those there found it hilarious and began using it as a response to anything in any and all circumstances. It became a highlight inside joke for
people into SpiffyJuice or the JCF.
reg ;) is used as a reply to absolutely everything, but is reserved sometimes for extraordinarily good circumstances. For the opposite, reg ;(
may be used though that's not very important either way.
