Oh my god

Jack (my brother) is playing with his friend in the other room and I swear, this is what I've been hearing:

Jack: 'don't tickle me, I'm ticklish all over'
Friend: 'Dude so am I'

Jack: 'NO NO you're still down stay down'
Friend: 'Kay'
Jack: 'YOU KNOW WHAT THIS MEANS YOU KNOW WHAT THIS MEEAAANS'

Jack: 'Dude, you okay?'
Friend: 'Yeah, but you missed.'
Jack: 'Oh, sorry'

Friend: 'DUDE OW, THAT'S TOO LONG OW'

Friend: 'HAHA That's tickles- OH THAT HURT'

I'M DYING OH MY GOD
