A word to describe a smart person, based off the world famous biologist, scientist, and philosopher Melvin Sneedly (from the show The Epic Adventures of Captain Underpants)
An amalgamation of the two words, seedy and needy. Generally when one has not masturbated or experienced sexual release for an extended period of time. Becoming sneedy can affect judgement i.e a 6 becomes a 9. Meaningless activities performed by a person(s) off the opposite sex make you become aroused.
