A pseudospoonerism of fucktard, it means the same, but is generally used when saying the "fuck" part would be frowned upon.

A f*in' retard so retarded that fucktard is too complicated for them, hence the spoonerism "tuckfard" which inverts the "t" and the "f" for maximum stupidity.
The guys started a food fight on spaghetti and meatball day to impress the girls at school. Unfortunately, it was also "wear all white" day so they were labeled "tuckfards" thence and for ever.
