You're not a critical thinker are you...
The people who captured the broadcast don't matter. We're all listening to the same audio lol. You think if someone records audio that they're more capable of hearing than others?
"Besides, do you realise how stupid it is, you think he's talking about kissing in a fight? There's no K sound, use your brain if your ears dont work."
There's about a million people talking about hearing a "k" sound. And it's pretty fucking ironic that you're talking about using a brain when apparently yours can't even think of how the word kisses would be used to trash talk lol.
Like the others are saying, he could be saying "only kisses" to make fun of Khabib's punches.
You're honestly hilarious dude, all of the point you made are silly. "THE UFC RECORDED IT!" irrelevant. "WHY WOULD HE SAY KISSES" lol..."There's no K sound!" when everyone's talking about a K sound.
Use the headphones like the guy above is suggesting. Also lookup the zanny laurel thing.
