I've noticed someone did this to me, they shook my friends hand first(slide+knuckle bump) then me(slide+open palm). At first i thought it was a sign of disrespect, but I don't know anymore.
The thing is this person always shakes my hand that way, and i see him shake other's the regular way(slide+knuckle bump)
