Thanks to @SimplyAwkward for this awesome suggestion!
Get out your history books, kids. This inside jokes dates back almost a decade ago in 2008.
In 2008, 5 stars were born in the form of SHINee. They released an album that is still one of my favorites and they started their climb to idol fame.
The very first song on their album though, went down in unusual history.
First off, this song is a JAM. But when you get to Minho's rap...something's a little...funny ;) Listen from 3:20-3:37^^
side note: omg i havent listened to this in forever and its throwing me back good lord!
He's just introducing the members, but something about this verse and the 'my name is minho' part blew up into an inside joke with both the fans and between the members themselves!
