this is an insult which can be used for someone who is suspect, or for anybody who is full of unneccesary shit.

the origins of this insult are from the episode of thomas the tank engine where thomas overheats and they put water from the lake in him, and he gets fish all in his tank!
dude, i don't believe that. you're such a fishy thomas.
