Cringeworthy moment man mocks woman wearing band T-shirt without realising who she is

If you're going to be that idiot who lampoons people for wearing band tees, then you'd better wise up before opening your gob.

A cringeworthy moment has exploded across social media after a man tried to mock a woman who was simultaneously minding her own business while sporting music merchandise.

The clipped interaction (lasting six seconds in total) went viral on TikTok, with the woman in question seeming visibly bothered by what she'd just had to contend with.

She was sat in a restaurant at the time, looking bowled over and amused by the fella's unsubstantiated brazenness.

"Guys, I was casually waiting for my food wearing my band's merch and a guy came up and asked [me] to name three songs," she'd typed over the screen.

"I don't know how I should feel about this," read her caption.

Incredibly, the woman (real name Jo Cotrotsou) was actually the lead singer of Greek indie rock band Bad Habits, who go by @whatisrocknroll on TikTok.

'Bad Habits' was emblazoned in pink on her sleeveless black T-shirt.

Even though the man had rudely questioned the musician about her own band's track catalogue, Cotrotsou was able to brush it off and have a laugh about it.

Other members of Bad Habits include Ellie (playing bass and also on vocals), Spiros (guitar), Severin (lead guitar) and Apostol (drums).

Formed in Athens six years ago, the group has over 14,000 followers on TikTok.

As you'd expect, fellow social media users flocked to Cotrotsou's comment section with their takes on the gaffe.

"People actually do this irl?? That's so embarrassing for them," wrote one disbelieving fan.

"I hope he sees this and gets so embarrassed he never asks anyone to name 3 songs again," read a second comment.

Meanwhile, a third TikToker suggested the tattooed rocker should've slapped the guy with a cheeky question of her own.

"You should have said, 'name the band members,'" they wrote.

Somebody else went on to reveal their personal experience with band tee naysayers: "I wore a Nirvana shirt to my kids school and their principal did this..."

"I stopped wearing band shirts because of this," noted another fan of Bad Habits. "Even my ex would do it about bands I introduced him to??"

With a little bit of luck, the merchandise questioner will have seen the ensuing video and learned to keep his mouth shut from then on. If not, hopefully he reads this!
