Definition of "Drarry"

It occurs because in canon Harry and Draco feel no emotion for each other warmer than intense dislike. […] Harry is willing to save Draco's life out of recognition of their shared humanity, but with apologies to all the Drarry shippers out there, that's as far as it goes.

Dramione shippers apparently feel the same way when too much attention is paid to Drarry.

Fanfics that depict relationships between Draco and Harry have been particularly popular, spawning a cult of ‘Drarry’ shippers – with Facebook pages, fan art and many stories all dedicated to the pairing.
