Repubrûlée

A non-American person (typically European) who actively aligns with the USA Republican party, be it through social media posts or demonstrations. Particularly used to refer to self-styled political pundits who are more focused on alt-right America than their true nationality.

"Brûlée" refers to the French baked-custard dish Creme Brûlée - the European equivalent of a Repubtard.
