That's just and she shared her ink in a video on TikTok. The tat, which is on her inner, upper arm, is of a cartoonish looking ghost with an open mouth, next to a palm tree.
However, the video was shared in response to another TikToker asking people to show off their most meaningless tattoos. So why did she put it there? Well she explains in the clip that while she thought her son made drawing, it turns out it was actually done by her son's friend.
