Twitter hashtags only have a couple purposes: track current conversational trends, and maybe keep people informed (or distracted).

But every now and then a poorly-worded phrase confuses the masses. Like Susan Boyle's anal bum party. Or, in this case, a hashtag about today's passing of former British Prime Minister Margaret Thatcher -- which oddly had Cher fans in an uproar.

We can understand the confusion. The hashtag #nowthatchersdead was meant to be parsed out as "now Thatcher's dead." But it can certainly look like "now that Cher's dead." Oops.

Equally confusing: A website that's apparently (and weirdly) been awaiting the Iron Lady's death is currently using the promotional hashtag #isthatcherdeadyet to promote the site. And no, it doesn't mean "is that Cher dead yet?"
