Title.. no other solid behaves like ice does.. you can’t stick ur tongue on a cold rock or stick two cold rocks together and they stuck together or slip on another solid rock.. why is that?

Because heat (from your tongue) and pressure (from stepping on it, which also creates heat) melts a bit of the ice, creating water. This little bit of water reduces friction, which makes it slippery. As for the stickiness: the now melted ice will re-freeze if it’s cold enough for it to do this, and so will the moisture on your tongue. This creates a new layer of ice, which makes it sticky.
I’m not sure what you mean by “stick ur young” but one of the things that makes ice sticky is that putting relatively low pressure on two pieces of ice causes some melting of the surfaces in contact, which then re-freeze together when the pressure lifts. Rocks might behave the same way but would need a lot more pressure to temporarily turn into a liquid at the point where the rocks are in contact.
Ice has a rough surface that can melt with the friction and temperature from both surfaces going against each other.
Ice is slippery when the temperature is low enough to have water over ice acting like a lubricant.
Ice is sticky when it is so cold that the water turns into ice faster than it can be warmed up from friction.
