A portmanteau of retard and keyboard, this term is used to describe moments where an individual has made grave errors in the SPAG of a typed sentence. Reboards can consist of simple typos such as teh, but can be far worse due to intoxication, sleep deprivation or general stupidity.

Reboard can also be used as a noun to describe a keyboard with poor design.
"Man, how did I misspell that?! I'm having a total reboard night!"

"Haha yeah, the MS Natural thing is a total reboard"
