Remember the last time a male friend rocked a pair of booty shorts simply so you could sit an exam?

Yeah, us neither but that's because we're not friends with Andrew Nguyen.

After being read the riot act on health and safety guidelines when it comes to science labs, Andrew's friend, Diana, was told she would need to find appropriate pants to gain entry to her lab exam.

And in a move which has seen him hailed a hero by thousands, Andrew lent Diana his pants so she'd be permitted to participate.

With no desire to roam the halls in a pair of girl's hot pants, Andrew decided to chill out in the bathroom and share his story on Twitter.

"My friend needed sweat pants in order to go in her lab and take a quiz so I'm just chilling in the restroom for 50 mins with booty shorts on," he wrote in a post which has been liked almost a quarter of a million times in less than 24 hours.

"That's a ride or die friend," wrote one Twitter user while another added: "What a great friend."

Unsurprisingly, some social media users couldn't pass up the opportunity to scorn Andrew's efforts, with one writing: "That's the definition of the FRIEND ZONE FOR LIFE."

Ah, shush! (We love you, Andrew!)
