Someone in marketing at KitKat HQ appears to be having a bit of a meltdown.
You did read that right. One of those Kit Kats actually reads banter.
No, Kit Kat. Banter is something people want a break from.
If printing the word "banter" on wrappers wasn't enough, there's now a hashtag on the actual chocolate. Just in case you felt the need to live tweet your KitKat experience.
There is still hope, though - offending wrappers have only been spotted on Kit Kats of the chunky variety so far. Normal size ones should still be safe.
