I used to have some friends who were jugglers, I’d hang out when they’d practice in the park and even learned a couple simple patterns. Occasionally someone would stop by and say hi and say that they were a juggler too or something. The only time anyone objected was when one of them started to juggle flaming torches at night, a security guard asked him to stop. But in general it was no more/less weird than throwing a frisbee. (this was in the midwest USA, dunno about other parts of the world.)
