To his credit, he did add "*rimshot*" at the end of his tweet. I don't expect everyone to know what it is because I haven't heard the actual term until a few years ago. A rimshot is that drum sound that is commonly played at the end of a punchline. So, I do think he intended it to be a joke... But it is a poorly conceived joke. If you have to explain it in 10 whole tweets to someone who is outside your intended audience... then you're just a very sad person seeking attention. Also being offended on behalf of other people is a common trait these people tend to share. Anyway, I can think of a better joke that is not nearly as long winded as this guy's joke.
Even if Vic has had Botox, he still emotes better than Monica Rial with her horse teeth. *rimshot*
