the snatching of a wig, but without enough snatchedness to take the whole thing right off. half-snatched wigs are usually caused by performances or events that one would describe as "pretty ok" or "sorta good," but lacked the extra bit of skinniness that snatches the entire fastened wig off the wig-wearer's head
skinny #1: yeah, i saw katy perry perform live once.
skinny #2: wow, how was it?
skinny #1: wig was only half-snatched and bitch had me pay $70 a ticket, no wonder her career is as dead as the real avril lavigne.
skinny #2: oh. rip.
