"Doing a Heidi!" is a insult that is directed at someone when they are acting like Heidi Rawling!

Heidi refers to being bitchy, annoying and generally high pitched! :P

Peace out!
"OMG your doing a 'Heidi'!"
"I'm what?"
"Such a Heidi!"
"Oh you mean Heidi Rawling?"
"Yeah"

Get the Doing a 'Heidi' mug.
Doing a Heidi Allen is generally described as opining on something you have no knowledge of and trying to support your position with factually incorrect data. It is also a term used to describe someone shamelessly self promoting.
Come on dude, that's clearly not a sensible thing to do; you're doing a Heidi Allen
