Fedtard refers to a fanatic Federer fan whose head is deep in horse-shit. He/she lacks the fundamental ability to reason. He/she is filled with hate specifically against Rafael Nadal. A Fedtard believes all tennis players whom Federer loses to and specifically Rafael Nadal use PEDS. Fedtards believe there is no evidence needed to support this claim because no evidence can be found.
Fedtards are retards who've gone full retard, and we all know: you should never go full retard.
Jake: Ruan's Federer blog is full of Fedtards.
Sally: Really ?
Jake: Yup, certified Fedtards.
