Wig snatching means that someone is blown away, shook, or freaking out because of something amazing. It is often a reaction to seeing an image of a hot person. The term originated from drag queens, who wear wigs, and is typically used by women and gay men. Wig snatching can also refer to someone being shocked by having shade thrown at them or being dragged.
