There is no Orthodox Christian custom to kiss people at the kiss of peace in the Liturgy (well, the clergy do, and anciently the people did, but that's a long time since, and the sexes were segregated back then always). Nor shake hands.
If anybody is doing that, they are trying way too hard to be Cool and Really, Like, Hip.
It will fall flat. If it's a Cool American Happening Thing, the fad won't last long.
Christ is risen.
