I can maybe see why those outside the UK may not have heard the term but the fact alone that her bio right under that says she is from London in the UK, maybe it's just me but if I see a term and it seems to be used in a weird context for my country I would Google it to see why it was used there, dirty burger etc is a common as fuck thing in parts of the UK and elsewhere and the idea that people jump right on attacking her when she actually did have a reasonable response to tell them that they maybe didn't understand the British slang, instead they could have maybe done a Google search, saw it was in fact slang and not related to any one culture or food type and maybe moved on, I don't get why this became such a big deal, especially when a quick Google search would have shown all different foods from all different cultures and backgrounds having the same term used, including basic ass English foods. Just seems like people got offended, saw her try and explain it then got more offended as opposed to actually checking for 2 minutes online if what she says was true, which again, is true. It's a common slang word and not used as an offensive word and again used on just as much British food as it is any other type.
