Negative hmm difficult. It was more indirect things like ignorant people saying cane dancing is not authentic and I should dance with an Arabic sword instead

. And if I can dance like Shakira and, concluding from a picture, I'm not bellydancing because my belly wasn't visible

. Worst insult though was by this bitch... I mean ex-fellow dancer, who said just before a performance she thought I looked older than 21. (Well I'm 23 now but you get the point).
Best complement, one of my teachers saying I had the same expression as some Egyptian dancer at a moment.
