Well, see, the entire incident would not nearly have been as funny if Laelith had only backed into another mob....
But nope! Ok, so the *ahem* n00b hunter in the group
sorta accidentally targeted the wrong mob and sorta sent his pet charging into a group of about 5. It was no biggie of course, other than said n00b hunter 
wanting to crawl under his desk and hide, except Laelith got aggro. In her attempts to not get hit while we all tried to get the mobs off of her she backed up...
....and into another group of about 5 mobs....
so was born getting "Lae'd", which not as good as pulling a Liro but from what I understand is slightly better than getting wizzed....
