An Aussie comedian has defended an unusual phrase said Down Under claiming the beloved Mexican Wave is completely innocent.

Monty Franklin, who left Australia to move to Los Angeles, explained the origin of the 'Mexican Wave' in a TikTok from February after realising the sporting icon had a number of names across the globe.  

Mr Franklin stuck up for the Aussie term in the video captioned: 'Things in Australia that sound racist but are not'.

After making the move to the US, he began noticing how many cultural differences there were between Australia and other countries and began working them into his comedy.

The stand-up comic poked fun at the odd inclusion of 'Mexican' when describing the friendly sporting-staple where crowds simulate the fluid motion of a moving wave. 

'You know "the wave" at sporting events that goes around and everyone does and has a wonderful time,' Mr Franklin said in the video.

'In Australia we call that "the Mexican wave" … I don't know why. There's no need to put Mexican in front of it.'

The comedian realised the term wasn't as common overseas when he came back to Australia with his American wife.

'They said "the Mexican Wave" on TV for the cricket, she said "why do you call it that?"', Mr Franklin told Daily Mail Australia.

'She thought it sounded funny, but I realised I had no idea why we called it that and I've never questioned it, it's just always been that.'

New Zealand is another of the few countries that use the term 'Mexican Wave' rather than just 'The Wave'. 

This prompted some investigative research from Mr Franklin, who found about the disputed origins of the term.

'First time commentators saw this wave was at the soccer World Cup in Mexico in 1986 so they started calling it the Mexican wave and it kind of stuck since then,' he said in the TikTok.

However, a comment on his video actually disputed Mr Franklin's research, claiming that it might've actually come about in 1979.

'The term was created by "Krazy" George Henderson in October, 1981 at the televised A's/Yankees playoff game in Oakland,' the commenter noted.

The Mexican wave was first documented in a 1981 video taken during a Major League Baseball game.

After that, it was introduced to the world at the 1984 Olympics when 100,000 fans created a wave during the football final.

The 1986 World Cup in Mexico is where the move gained global prominence when crowds would do it at least once every game.

This is how the 'Mexican' description was introduced into Aussie lexicon, as many around the world saw it for the first time during the 1986 World Cup.

Mr Franklin said many Mexicans gleefully reached out to him after he posted the video, which has since been viewed more than one million times. 

'I had thousands of Mexican people who reached out to me on Instagram that thought it sounded hilarious but they just call it La Ola which is "the wave,"' he told Daily Mail Australia. 

The Mexican wave isn't the only oddity he's discovered since moving to the US.

'You know the Americans have a thing called Aussie cheese fries - French fries covered in cheese- I've certainly never heard of this back home', he said.

'As an Australian living in America I say a lot of things sound odd and raise eyebrows.

'Flat white is another odd one.'
