A person that asks way too many obvious questions. The questions asked could easily be found by the Sid, but the Sid would rather ask other people, continuesly. If the Sid gets ignored or gets no answer in return, he responds with "what?", pretending that someone did actually say something that the Sid just didn't hear. Sid's are typically referred to the Google website.
Me: Hey man, try this soda!
Sid: Thanks dude *grabs soda*. How much sugar is in this soda?
Me: Try looking on the back of the can, Sid.

Sudden Infantile Dumbass Syndrome. Occurs when an adult baby is placed in time out and loses a toy and he tries to get it unsuccessfully, and he gets hurt or dies because of it
When Barnaby was placed in time out, he discovered that he had lost his teddy bear. As he reached out of his adult-sized crib to get it, the crib closed on his neck crushing it. He had died suddenly of SIDS. He should have waited for his wife to come back after he had cooled off from his tantrum.
