Actually I love Vegemite. My late husband compared it to axle grease and said he hated it. Strange statement when he had never ever tried it. I was brought up on it and I am what we Aussies call, a Vegemite Kid.
Back in 1983 when I was visiting my daughter, MotherGoose, who at that time was living in California, I went armed with a large giant sized jar of vegemite for her as she could not buy it there and missed having it, plus two Tee-shirts, one each for her and her husband which carried the slogan "I'm a Vegemite Kid" They were amused and when we visited an amusement park a few days later they both wore them. As we were walking along an American woman came up to us, stared at their Tee-shirts, and said in a loud voice (drew the attention of by-standers by the way) "I'm a Vegemite Kid! What the hell is Vegemite?" Created quite a bit of amusement.
My advice to others "If you haven't tried it, don't knock it till you do". I am never without it on the kitchen counter to plaster on my morning toast....LOL
