When You Try Spelling Reatarded When You're Half Asleep

Retard spelling of "retard."

Retarded spelling of retard wrote by a retard, for example: Ethan

i am going to kms

i mispelled it

Used as an ironic insult to mock the fact that they are retarded and cannot spell. If they don't understand that you made the mistake on purpose, then the insult is further confirmed.
