"Like" as a form of punctuation.
It is, if anything, even more annoying when said in its original Californian intonation.

In fact, the Californian accent in general. I would be more than happy if that state and all its shallow inhabitants mysteriously sank into the ocean.

Me and my brother do this
We're not sure why, as we've never shown this behaviour with anyone else...

Worse still,
"Like" as a substitute for "said," or any of the other myriad alternatives that our beautifully rich language offers. Your protagonist could have "replied", "retorted", "cried", "yelled", "exclaimed", "ejaculated" (fnar fnar), "shouted", "suggested", or one of many other possibilities, and yet all you can muster is,
"So yeah, he was, like, 'No way, man!'
And I was, like, 'Fuck you, man!'"

"No, actually I don't know what you mean because you are talking incomprehensible shit," is an honest response that sadly doesn't win you many friends.
