There's a difference between "making out with each other" and "playfully grabbing each other".
-Kissing: sign of affection, not just reserved for the opposite sex. In some countries, a small peck on the cheek(s) is a standard greeting.
-Grabbing each other: some girls get to the point in their friendships that they are comfortable with being grabbed in an affectionate way by other girls. What you may see as manhandling, they find perfectly acceptable.
