fishiest

Most dubiously questionable

Fishiest is the superlative form of fishy, meaning the most suspicious or dubious of a group.

If something smells fishy, it arouses doubt or mistrust, and the fishiest option is the one that seems most questionable.

Of all the excuses I've heard, that one's the fishiest.

The literal sense—having the strongest fish odor or most fish-like qualities—exists but is far less common than the figurative use suggesting something isn't quite right.
