Fans put the slipper into the Cup's boy who cried wolf after his nation was booted from the World Cup in the quarter-finals, launching a viral meme — the Neymar challenge — on social media.
Thousands took pleasure in mocking the international superstar as the #NeymarChallenge hashtag exploded on Twitter.
Mexican Liga MX side Club Tijuana took Neymar down a peg with almost every player on their team rolling down the pitch as halftime entertainment during their match against Herediano over the weekend.
The announcer can be heard excitedly yelling "Neymar Challenge!" over the ground's PA system as hundreds of fans cheered on.
Portuguese National Institute of Medical Emergencies (INEM) put the slipper in particularly hard, using Neymar as the face of their advertising campaign detailing the harm in making illegitimate emergency calls.
The caption warns viewers that over 75 per cent of phone calls made to their offices could be avoided.
"75.8 per cent of calls to 112 are not emergencies," the post — which was liked and retweeted over 10,000 times by gleeful fans — read.
In Neymar's defence, he did reach the quarter-finals, a feat not achieved by blockbuster names Messi and Ronaldo, who both dramatically exited the competition within hours of each other as Argentina and Portugal went down in the round of 16.
But Brazil's exit still came as a shock.
The 2014 hosts and five-time champions fell in an upset on Saturday as underdogs Belgium tore through the favourites 2-1 at Kazan Arena.
