The most brutal thing anyone can ever type to a person. Often used when annoyed or pissed off at someone or tend to be used by bitches. This is a KDOT:
Mouse: Ohmygod, Amanda is being such a bitch. I wanna slap her so badly and leave a mark on her face.
K-Chum: I'm sure it's nothing, it'll be over within a week..
Mouse: She KDOTTED me..
K-Chum: Then by all means, SLAP THAT BITCH.
Mouse: YOU'RE SO AMAZING :)
