There's usually a generic pattern to weigh-ins in UFC. You get yourself weighed, your opponent gets weighed, then you stare each other down for the final time before meeting inside the octagon for your fight.

While you might from time to time get the odd occasion where a fighter has to strip in order to make the required weight or scuffle between fighters, rarely do you get a situation which occurred during Kevin Lee's weigh-in on Friday night for his lightweight fight against Francisco Trinaldo at UFC Fight Night 106 in Fortaleza, Brazil.

It's an experience The Motown Phenom probably won't be forgetting anytime soon.

As the American stood on the scale to be weighed in, the Brazilian crowd began chanting towards him 'Uh vai morrer', which roughly translates into English as 'you're going to die'. As you would expect, Lee wasn't having any of it.

He retaliated to this by putting his hand over his mouth to cover his smile and laughter and flipped off the crowd by giving them the middle finger, which caused the crowd to respond with a chorus of boos before one of their very own in Trinaldo walked onto the stage for his weigh-in.

The rude hand gesture happens very early on in the clip below, but when the two fighters come face to face later on, the chants of 'Uh vai morrer' directed towards Lee gets louder and louder. Watch out for Octagon girl Camila Oliveira's great shocked reaction to The Motown Phenom's rude gesture as well.

The clash between Trinaldo and Lee is only on the preliminary card at UFC Fight Night 106, as the fight between middleweights Vitor Belfort and Kelvin Gastelum headlines the event.

The Motown Phenom and Massaranduba have very different fighting styles, so it could turn out to be one of the more interesting fights inside the octagon this weekend. The Brazilian is more favorable towards striking as 33% of his fights have ended via KO or TKO. The American, however, prefers takedowns and submissions as 43% of his contests have ended in that way.

A win for Lee could be a way for him to break out at lightweight, as Trinaldo is the 11th ranked fighter in the lightweight division.
