when you're so high that you almost feel unable to move your muscles. everything feels weird and you kind of just sit back with your mouth agape staring off into space and enjoying it. contrary to popular belief, "stoned" and "high" are different in that, the word "stoned" originated from the idea that you feel like you're being weighed down by big heavy stones.

Extremely high off indica weed. Indica has muscle relaxers and natural pain killers which gives you a major body high, when you have a major body high you feel like your numb, heavy, relaxed, calm, and/or tired. When your indica high(say you smoked some purple kush) you will be sitting on the couch heavy as a stone(hence the "stone" in stoned), also it can blur your vision and give extreme euphoric feelings and elevated thinking.
If you are high on sativa weed it wouldn't be a stoned type of high it would be more head high, head highs are more about thoughts then feelings in your body. The euphoric aspect of sativa is a lot less intense than indica. The feelings of sativa are upper related, sensitive touches feel great, you feel light as a feather(hence the word high, meaning people feel like they are floating), hyped, energetic, and/or awake.

when you smoke so much marijuana that you are unmotivated to even move- and every muscle in your body feels like it's being weighed down by a huge weight like a stone (hence the word STONED) you feel really heavy and have intense, very enjoyable tactile hallucinations and usually feel complete euphoria so you just stare off blankly and enjoy it.
