Brendon McCullum might not have thought that his elder brother and former Kiwi cricketer, Nathan will roast him on Twitter after posting his childhood picture. Junior McCullum posted a picture on social media and wrote, "Born Thirsty" as the caption. 

A chubby Brendon can be seen having his drink in the picture with a straw. Taking a jab at him, Nathon wrote, "Glad you got rid of the puppy fat bro! Not many people could say they did a strawpedo at 6 years old????????????". 

Not the first time that the senior McCullum pulled junior's leg. During last year's BBL Nathan had tweeted not to give bowling to Brendan, knwoing that he will brag about it if he manages to get a wicket.

"Don't let Baz bowl in the BBL," the 37-year-old tweeted.

36-year-old Brendon McCullum is playing Pakistan Super League (PSL) currently. His team couldn't perform as per expectations and hence the former New Zealand cricketer offered to quit captaincy if needed.

"Ultimately as captain, you're responsible for the performances. I feel like I've done the same things that I do in any team that I've led, but unfortunately, that hasn't resonated. So that's the question we've got to ask tonight as well - whether it's better offloading it to someone else and seeing if we can get better results. Doesn't matter if you're saying the right things, but if they're not hitting home or the instructions aren't being followed, then you're always going to be pushing it uphill," he had said.
