Jubilant Indian fans spilled out onto streets and let off firecrackers after the national team defeated bitter rivals.
In bars, restaurants and homes nationwide, millions watched Virat Kohli score a majestic 107 before his side cruised to an emphatic 76-run win at the jam-packed Adelaide Oval.
Across the border, the mood was a mirror image.
Pakistanis nationwide watched the match either at home or in restaurants with specially installed big screens, but left downhearted.
Fans slammed their team after a 76-run defeat to arch-rivals India in their opening World Cup match in Adelaide on Sunday, claiming their beloved team can't bat, bowl or field.
They installed giant TV screens, but the defeat - the sixth in six World Cup meetings - frustrated them.
Indian fans seized this opportunity and swamped WhatsApp, Facebook and Twitter and other social media platforms trolling Pakistani fans.
Numerous jokes started doing the round on the internet; some of them targeting Pakistani players.
To top the list was the one-minute ad showing a Pakistani cricket enthusiast witnessing all the losses of Pakistan to India and never been able to burst crackers to celebrate.
